Mike,
I think I'll use the same method to paint my fillets, but I believe I'll use a catalyzed primer to fill the seam. I tried using spray cans but the build up is insufficient and it takes too long to dry.
I've balked at the elastic flying wires but after trying a few various methods, wire and kevlar, I think I'll go with elastic.
What prop did you use on the .72?

Jacs,
I removed the Coverite because I wasn't satisfied with the surface. After I tried to cover the seams and did a little sanding I ended up going through in a few places because of high spots. I removed the covering and did some more sanding and now I will cover it with yellow SolarTex.
As far as the fuel filler goes, I'm a beliver in simple is the best. I'll probably run the fuel filler tube to the bottom of the cowl and use a dubro plastic plug. I've used them before with good results.
As far as the talc in the paint, I use to work in the Automotive paint business and talc is a basic flattener. Just make sure it's mixed with the proper amount of reducer. The talc was mixed with a clear and this mixture was added to the color. It also can be added to the clear.
