(Matt Dralle) ________________________________ Message 1 _____________________________________ Time: 05:12:32 PM PST US From: Matt Dralle Subject: RV8-List: Interior Painting - Powercoating? 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...

Installation of the roll servo for the TruTrak autopilot was pretty straight forward. The system seems to work well and doesn't add any noticeable drag to the aileron stick forces. Fortunately, it just fit in with the Electric Aileron trim setup. I actually had to move the control horn on the stick column forward about 1/8" to assure that there wasn't any interference between the rod end bolt and the left spring. Seems two work fine and there is no binding or rubbing of any kind. Sweet.
