Definition of Insanity (Robert Reed) ________________________________ Message 1 _____________________________________ Time: 06:29:17 PM PST US From: Robert Reed Subject: KIS-List: Definition of Insanity =0AWhere is everyone?- This list has been very quiet for too long.- =0A =0AI have often heard the definition of insanity is doing the same thing ov er and =0Aover expecting a different result.- Well, based on that definit ion I am clearly =0AINSANE.- =0A=0A=0AI always try to do my research on a ll the options before I undertake doing =0Asomething.- I try to plan ahea d and consider all the issues before making a =0Adecision on how to best ac complish the task at hand.- That is exactly what I did =0Awhen I decided how I was going to get the plane painted.- The airport where I =0Ahave th e plane doesn't allowing spray painting in the T-hangars and doesn't have =0Aa paint shop on the field.- That combined with me not having a paint s hop at =0Ahome led me to research alternatives.- After looking at many di fferent =0Aalternatives and paints I found the System Three Paints-which are highly =0Aregarded for fiberglass boats and yachts use.- First, the p aints are water based =0Apolyurethane-with very low VOC's.- Secondly th ey are formulated for either spray =0Aor Roll & Tip application.- My plan was to use the Roll & Tip for the Primer and =0Afor the Color Coat.- Fol lowing that, I had decided to try and spray the clear =0Ahigh gloss coating .=0A=0AI had already put three coats of primer on both wings some time back and the =0Aprimer went on very smooth using the roll and tip.- I had som e issues with the =0Aprimer drying a bit too fast and-by the time I got t hrough the bottom side of =0Athe wing it appeard to show some brush marks. - The primer sanded down well =0Athough and the brush marks disappeared. - Now this is where the trouble starts =0Aand insanity rules.- After I primed the wings I started to SECOND GUESS my =0Adecisions.- I bought a s econd tank for my compressor, bought some HVLP spray =0Aguns, additional ho se, filter, and decided to spray the color coats instead of =0Ausing the ro ll and tip.- Now I know and have known for many years that every =0Asingl e time I have Second Guessed myself the results have always been BAD but =0Aonce again, I did it.=0A=0AI took the week off last week to try and get something done on the plane.- My =0Aplan was to get at least one wing ful ly painted and possibly a bit more =0Aaccomplished too.- Both wings were already primed so I took a day to sand and =0Aprep-one wing.- Next I ne eded to clean out the shop so that I had some room to =0Amove around withou t falling all over everything.- With two wings, the wing cart, =0Aflaps, ailerons, doors, rudder, elevators, and all of my tools crammed into the =0Ashop,-something had to give.- The first to give was the car in the g arage.- =0AMoved most of the stuff into the garage.- =0A=0A=0AThen I bo ught a bunch of 3/4 inch PVC pipe, a lot of plastic sheeting, and =0Afabric ated a makeshift paint booth inside the shop.- It actually looked pretty =0Agood when finished but took way too much time.- Finally, I mopped, mop ped, and =0Amopped the floor until I got the sanding dust and dirt cleaned up.- After =0Aletting the shop set overnight with the airconditioner runn ing to let any =0Aremaining dust settle and filter out,-I wet down the fl oor and prepared the =0Apaint for spraying.- I had already tested the spr ay guns for pattern and =0Aeverything looked OK as far as I could determine .- I sprayed the first coat of =0Acolor with what seemed like a light coa t but the coverage wasn't good and it =0Aseemed spotty.- The spray drops had not joined and there was no flow out.- I =0Afigured the second coat w ould fill in the color but needed a touch more =0Athinning.- The Second c oat seemed to be going on much better with good coverage =0Aand I moved dow n one side of the wing and then the other.- The wing is hanging =0Afrom t he ceiling and as I was painting everything looked good, no visible runs. - =0AAfter I finished the-bottom side, I looked down the wing and it lo oked great.- I =0Adisconnected the gun and went outside to clean the gun very satisfied with the =0Aapparent result.- =0A=0A=0ATen minutes or so l ater after cleaning the gun with water and air I went back =0Ainto the shop .- What I saw was enough to make this grown man cry.- There were =0Arun s everywhere!!!!!!!!- Both the Top and the Bottom of the wing had runs an d =0Abald spots where the paint had simply slipped off the surface and down the =0Awing.- It was the WORST paint job ever.- I am not sure if I put too much paint =0Aon, thinned it too much, or what but it was a total disa ster.- I knew the only =0Athing I could do was let the paint dry, sand it down and either re-prime or try =0Aagain.- Now the one thing that the Sy stem Three paint is well know for is being =0Aa very tough finish and I am here to testify to that point.- If the crosslinker =0Ais added to the col or coat it forms a very HARD, durable, and chemical (gas) =0Aresistant fini sh.- What that means to me is a finish of runs that are first =0Acousin t o trying to sand concrete.- This paint is tough and sanding it down took =0Aall day long with a power sander.- I never did get all the paint off b ut did get =0Ait smooth again.- Since that much sanding cut through some of the primer as well =0AI had to reprime the wing with two additional prim er coats.=0A=0AI was frustrated and angry with myself for second guessing w hat I decided to do =0Aand I payed the price.- I tore down the paint boot h-plastic and PVC, cleaned =0Aeverything up and spent the rest of the wee k priming all the other parts with =0Athree coats of primer.- If I can ge t the color coats to go on as smooth as the =0Aprimer the paint job will lo ok great.- The primer is so smooth (NO RUNS)-that I =0Awill only have t o do a very light sanding before putting on the color.- I didn't =0Aget a nything fully painted this week but all the removable parts (Wings, doors, =0Aflaps, ailerons, elevators and rudder) have been primed with three coats .- Next =0Aweekend I will sand and touch-up any issues but will wait for the-next weekend =0Ato start color again.- This time, I will NOT SECOND GUESS my decisions and I =0Awill not get in a rush.- Three light color c oats using the roll and tip =0Aapplication on the first day.- Sand and to uch-up if necessary with 600 grit wet =0Apaper and follow with two or three coats of Clear Gloss coating on the second =0Aday.- The cross linked pai nt is best applied within 24 hours or full sanding is =0Arequired.- =0A =0A=0AFinally, if necessary I will color sand, compound, and buff finish. - It will =0Atake a lot more time, a lot more work sanding, sanding, sand ing, and some more =0Asanding but I hope the results will be worth it.- W hat it won't involve is more =0Asecond guessing.=0A=0ANOW TELL ME AGAIN WHY I DIDN"T BUILD AN RV-6?=0A ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kis-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/KIS-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kis-list Browse Digests http://www.matronics.com/digest/kis-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
