When? Fellow RV-er's, There is a powercoating shop here in my town that has an oven large enough to put my whole RV-8 fuselage into it. I've been considering just having the whole inside powercoated for the durability, and sweet look. Lots of guys powercoat the instrument panel and obviously most of the steel parts come from Van's powercoated. But what are the upsides and downsides of powercoating all of the interior parts. I've used Variprime on most of the backsides of the interior parts, but I've left the occupant facing parts bare in prep for the powercoating. Will the powercoat chip off easily on the bend-y pieces? And when's the right time to take it down to the powercoaters? I would like to have most things riveted that need riveting before the coating like the forward deck over the instrument panel and the aft turtledeck, but these get riveted on pretty late in the building process. I would like to have all of the wiring and controls installed or at least fabbed and trial fitted before coating to avoid scratches. But again, once things are wired, is coating going to make a mess? Its not like the harnesses can really be removed once their installed... The other concern is the heat necessary to bake on the powercoating. I think its upwards of 450 degrees F. What impact will that temperature have on the various parts that go into the fuselage such as the aeronuts, plastic bushings, clamps, etc? I'm in quite a dilemma over this. I really want to wait as long as possible to avoid scratches and chips in the powercoating, but I don't want to wait too long and not be able to disassemble things to the point of making a good looking job. For example, the rear floor boards should probably be riveted down, but any screwed in panels should be removed. But riveting the floorboards is something I'd probably prefer to do the day before test flying... Thanks for any insight...

Dear Listers, I made a trip over to FinishMasters a couple of weeks ago for some painting supplies. I've traditionally also purchased my Variprime from these guys as they are an auto-paint store. On this last visit, I asked where the Variprime was and was told that "it is no longer available". It that really true? I love Variprime; it goes on easy and is thin enough to make a light protective coat with very little build up. I'm sure there are other primers that are just as good but I'd just assoon stick with what I know at this point. I have about 1/3 of a gallon left which might get me through the rest RV-8 project I've got going, but maybe not. It would be nice to find another supplier. Thanks in advance for the tips...

What impact would the powder coat oven (450*?) have on the heat treating of the aluminum alloy? There are several good paints that work very nicely in the interior of our planes. Sam Buchanan ________________________________ Message 6 _____________________________________ Time: 07:42:29 PM PST US Subject: RE: RV-List: Interior Painting - Powercoating? When? From: Brad Templin Disturbing the heat treatment is the problem with powder coat for something like this. 43.13 4-54b says: "Reheating of 2017 and 2024 alloys above 212 F tend to impair the original heat treatment. Therefore, reheating above 212 F, including the baking of primers, is not acceptable without subsequent complete and correct heat treatment." I have a decent sized powder coating setup in my garage and I powder coat LOTS of stuff for aircraft, but I do always try to be mindful of this. I asked a good friend who is in the heat treating business if this was fact or fiction. He indicated that it could start the change the heat treatment of those alloys and he would avoid doing it. For some little bracket or whatever it should be fine, but I don't think I'd do it on the airframe. Brad > > > Dale Ensing wrote: > > > > Matt, > > I agree with Jim.

Will the power coat chip off >easily on the bend-y pieces? Powder Coating is like baked enamel it is very hard to chip. Will add lots of weight and like you said it bakes at very high temps, which would most likely distort your panels, melt wiring connectors and all of your wire tie straps. It goes on in dust form so it will get around all corners and into places that you don't want like maybe the wing slots that may be too tight to except the wing spar after that. Just my 2 Cents Ken S. RV 6A Flying Europa XS Under Construction Thanks for any insight...
