Like I said in an earlier post, we didn't like the way the green looked after it was sprayed. Had nothing to do with the paint but it was our prep of the surface. We believe after wet sanding the primer and then priming again, then sanding again that we're not getting some of the "mud" created from the wet sanding out of the weave in places that the resin didn't quite fill. Even though the surface looks completely smooth with no blemishes, when the color is sprayed it lets those areas "gas out" so to speak.
Gerry always vacs the surfaces after wet sanding then gives a quick Acetone wipe down but I believe we need to apply some high pressure air to the whole surface to blow any sanding residue out of the weave so the next primer coat can fill them in. This of course is one theory. Another theory is we use 3M 77 spray lightly applied on the glass cloth to just tack it down when first applied to the bare wood. This prevents the cloth from moving around when the resin is first applied. On this plane I brought my own can of 3M 77 but it was an older can with the long gone blue label. It is the original formula that actually wasn't bad to use on foam. The new Super 77 cannot be used to skin foam wings but has never given us any problems. Not sure if this old formula Super 77 is to blame for the "gassed" out areas.
Took the re-sprayed top of wing and distressed it with 600 steel wool to give it a dull shine but weathered look. Came out real nice and the whole plane will get a very light gray wash for the true weathering effect blending everything together. After the steel wool the wing feels like a fiberglass finish. Real happy with the vertical fin and stab area. The fillet blended so well with the bondo that it looks like a molded fiberglass fuse. Also sanded down the fuse as it had some of the same issues the wing had and got it repainted today. It too came out real well and will get the same steel wool treatment. I've been doing all of the repainting and Gerry wanted to get a picture of me actually using an airbrush. Maybe some day I'll get the hang of it! LOL Here are pictures of yesterdays and today's work.
