 Posted: Sun Jun 02, 2013 5:29 pm Post subject: Definition of Insanity |
 |
|
Where is everyone? This list has been very quiet for too long.
I have often heard the definition of insanity is doing the same thing over and over expecting a different result. Well, based on that definition I am clearly INSANE.
I always try to do my research on all the options before I undertake doing something. I try to plan ahead and consider all the issues before making a decision on how to best accomplish the task at hand. That is exactly what I did when I decided how I was going to get the plane painted. The airport where I have the plane doesn't allowing spray painting in the T-hangars and doesn't have a paint shop on the field. That combined with me not having a paint shop at home led me to research alternatives. After looking at many different alternatives and paints I found the System Three Paints which are highly regarded for fiberglass boats and yachts use. First, the paints are water based polyurethane with very low VOC's. Secondly they are formulated for either spray or Roll & Tip application. My plan was to use the Roll & Tip for the Primer and for the Color Coat. Following that, I had decided to try and spray the clear high gloss coating.
I had already put three coats of primer on both wings some time back and the primer went on very smooth using the roll and tip. I had some issues with the primer drying a bit too fast and by the time I got through the bottom side of the wing it appeard to show some brush marks. The primer sanded down well though and the brush marks disappeared. Now this is where the trouble starts and insanity rules. After I primed the wings I started to SECOND GUESS my decisions. I bought a second tank for my compressor, bought some HVLP spray guns, additional hose, filter, and decided to spray the color coats instead of using the roll and tip. Now I know and have known for many years that every single time I have Second Guessed myself the results have always been BAD but once again, I did it.
I took the week off last week to try and get something done on the plane. My plan was to get at least one wing fully painted and possibly a bit more accomplished too. Both wings were already primed so I took a day to sand and prep one wing. Next I needed to clean out the shop so that I had some room to move around without falling all over everything. With two wings, the wing cart, flaps, ailerons, doors, rudder, elevators, and all of my tools crammed into the shop, something had to give. The first to give was the car in the garage. Moved most of the stuff into the garage.
Then I bought a bunch of 3/4 inch PVC pipe, a lot of plastic sheeting, and fabricated a makeshift paint booth inside the shop. It actually looked pretty good when finished but took way too much time. Finally, I mopped, mopped, and mopped the floor until I got the sanding dust and dirt cleaned up. After letting the shop set overnight with the airconditioner running to let any remaining dust settle and filter out, I wet down the floor and prepared the paint for spraying. I had already tested the spray guns for pattern and everything looked OK as far as I could determine. I sprayed the first coat of color with what seemed like a light coat but the coverage wasn't good and it seemed spotty. The spray drops had not joined and there was no flow out. I figured the second coat would fill in the color but needed a touch more thinning. The Second coat seemed to be going on much better with good coverage and I moved down one side of the wing and then the other. The wing is hanging from the ceiling and as I was painting everything looked good, no visible runs. After I finished the bottom side, I looked down the wing and it looked great. I disconnected the gun and went outside to clean the gun very satisfied with the apparent result.
Ten minutes or so later after cleaning the gun with water and air I went back into the shop. What I saw was enough to make this grown man cry. There were runs everywhere!!!!!!!! Both the Top and the Bottom of the wing had runs and bald spots where the paint had simply slipped off the surface and down the wing. It was the WORST paint job ever. I am not sure if I put too much paint on, thinned it too much, or what but it was a total disaster. I knew the only thing I could do was let the paint dry, sand it down and either re-prime or try again. Now the one thing that the System Three paint is well know for is being a very tough finish and I am here to testify to that point. If the crosslinker is added to the color coat it forms a very HARD, durable, and chemical (gas) resistant finish. What that means to me is a finish of runs that are first cousin to trying to sand concrete. This paint is tough and sanding it down took all day long with a power sander. I never did get all the paint off but did get it smooth again. Since that much sanding cut through some of the primer as well I had to reprime the wing with two additional primer coats.
I was frustrated and angry with myself for second guessing what I decided to do and I payed the price. I tore down the paint booth plastic and PVC, cleaned everything up and spent the rest of the week priming all the other parts with three coats of primer. If I can get the color coats to go on as smooth as the primer the paint job will look great. The primer is so smooth (NO RUNS) that I will only have to do a very light sanding before putting on the color. I didn't get anything fully painted this week but all the removable parts (Wings, doors, flaps, ailerons, elevators and rudder) have been primed with three coats. Next weekend I will sand and touch-up any issues but will wait for the next weekend to start color again. This time, I will NOT SECOND GUESS my decisions and I will not get in a rush. Three light color coats using the roll and tip application on the first day. Sand and touch-up if necessary with 600 grit wet paper and follow with two or three coats of Clear Gloss coating on the second day. The cross linked paint is best applied within 24 hours or full sanding is required.
Finally, if necessary I will color sand, compound, and buff finish. It will take a lot more time, a lot more work sanding, sanding, sanding, and some more sanding but I hope the results will be worth it. What it won't involve is more second guessing.
NOW TELL ME AGAIN WHY I DIDN"T BUILD AN RV-6?

Wow, sounds like quite an ordeal. My airport also does not allow painting in a hangar either. I painted my airplane outside on low wind days one part at a time. It sounds crazy but it worked fine and after color sanding and buffing it looks great. I had a similar run experience in places. I had pretty good luck scraping the runs down with a razor blade and then sanding and buffing them out, but I had to sand and repaint some of it. Lots of thin coats with 10-15 minutes of drying time between coats worked best for me.

Going to do all the sanding this coming weekend and then try a couple of small pieces with the roll and tip of color coat to get the feel of the paint and how it flows out. If all goes well then will attempt the wing again. At least with the roll and tip I know I can control the thickness of each coat. Color sanding will probably be the rule but I know it works.

Then I bought a bunch of 3/4 inch PVC pipe, a lot of plastic sheeting, and fabricated a makeshift paint booth inside the shop. It actually looked pretty good when finished but took way too much time. Finally, I mopped, mopped, and mopped the floor until I got the sanding dust and dirt cleaned up. After letting the shop set overnight with the airconditioner running to let any remaining dust settle and filter out, I wet down the floor and prepared the paint for spraying. I had already tested the spray guns for pattern and everything looked OK as far as I could determine. I sprayed the first coat of color with what seemed like a light coat but the coverage wasn't good and it seemed spotty. The spray drops had not joined and there was no flow out. I figured the second coat would fill in the color but needed a touch more thinning. The Second coat seemed to be going on much better with good coverage and I moved down one side of the wing and then the other. The wing is hanging from the ceiling and as I was painting everything looked good, no visible runs. After I finished the bottom side, I looked down the wing and it looked great. I disconnected the gun and went outside to clean the gun very satisfied with the apparent result.
Ten minutes or so later after cleaning the gun with water and air I went back into the shop. What I saw was enough to make this grown man cry. There were runs everywhere!!!!!!!! Both the Top and the Bottom of the wing had runs and bald spots where the paint had simply slipped off the surface and down the wing. It was the WORST paint job ever. I am not sure if I put too much paint on, thinned it too much, or what but it was a total disaster. I knew the only thing I could do was let the paint dry, sand it down and either re-prime or try again. Now the one thing that the System Three paint is well know for is being a very tough finish and I am here to testify to that point. If the crosslinker is added to the color coat it forms a very HARD, durable, and chemical (gas) resistant finish. What that means to me is a finish of runs that are first cousin to trying to sand concrete. This paint is tough and sanding it down took all day long with a power sander. I never did get all the paint off but did get it smooth again. Since that much sanding cut through some of the primer as well I had to reprime the wing with two additional primer coats.
I was frustrated and angry with myself for second guessing what I decided to do and I payed the price. I tore down the paint booth plastic and PVC, cleaned everything up and spent the rest of the week priming all the other parts with three coats of primer. If I can get the color coats to go on as smooth as the primer the paint job will look great. The primer is so smooth (NO RUNS) that I will only have to do a very light sanding before putting on the color. I didn't get anything fully painted this week but all the removable parts (Wings, doors, flaps, ailerons, elevators and rudder) have been primed with three coats. Next weekend I will sand and touch-up any issues but will wait for the next weekend to start color again. This time, I will NOT SECOND GUESS my decisions and I will not get in a rush. Three light color coats using the roll and tip application on the first day. Sand and touch-up if necessary with 600 grit wet paper and follow with two or three coats of Clear Gloss coating on the second day. The cross linked paint is best applied within 24 hours or full sanding is required.
Finally, if necessary I will color sand, compound, and buff finish. It will take a lot more time, a lot more work sanding, sanding, sanding, and some more sanding but I hope the results will be worth it. What it won't involve is more second guessing.
NOW TELL ME AGAIN WHY I DIDN"T BUILD AN RV-6?

Hello Robert,
I commend your perseverance in choosing an environmentally friendly coating for your project. You may be confusing insanity with Murphy’s Tech law which states: New systems generate new problems. At this point in your project I am sure you have overcome many problems and I am confident you will overcome this one. Ironically in this month’s issue of Sport Aviation is a tech tip on sanding which by now you could write volumes on the subject. It would be really cool if you had you Cruiser at Oshkosh for 20th anniversary of the design (2014). To redirect your perspective a bit I jotted down this top 10 list for you:
Top ten reasons building a KIS is better than building an RV
10. Geez, everyone else is building an RV. RVs cheap airframe price draws builders to this old technology but builders pay when it comes to the power plant.
9. KIS aircraft perform better with much less horsepower than RVs.
8. The smaller engines used on KIS aircraft yield a smaller fuel bill.
7. As long as the builders Keeps-It-Simple, time to assemble KIS aircraft is considerably less than putting an RV together.
6. KIS aircraft are infinitely more customizable than ANY RV. RVs are built according to plan. Building a KIS you can glue in the components and other modifications wherever you want with ease.
5. Setting 10s of thousands of rivets will drive wife mad as well as the neighbors too.
4. No helpers are required to do composite lay-ups. RVs may require the wife to buck rivets - would you really want to burn your favors this way?
3. Applying the finish to a KIS has less steps – metal requires etch, alumi-prep, zinc chromate or another type of protection coating, primer one, primer two, and color coat. Composite requires filling the weave, primer one, primer two, and color coat. As it is best that coatings cure together I show two primer coats as a good place to break between coatings. It would be difficult if not impossible to lay down all the coatings at one time.
2. KIS TR-1 is stronger than a RV 6.
1. At any fly-in a KIS will stand out more than the dime a dozen RVs (seen one RV seen them all).
PS: Two weeks ago I was able to assemble enough crew to get my McCormick TR-1C off the trailer and put away. The wing is in my garage and the fuselage is in my shed. Now I will be able to assess the condition of the airplane in full.
