I am just finishing re-covering and painting a large 85" scratch built high wing. I used Oz cover from Saturn Hobbies to recover and am impressed with it. Very tough material. Not as flexible as monocote or fabric, but if you don't have a lot of compound curves it works great. Just about impossible to burn a hole in it.

I wiped it down with acetone and scuffed with 400 wet or dry. I used all Rust Olieum paints. However, I added 1 oz PPG OMNI MH 101 hardner to each 4 oz of paint and thinned whth OMNI general purpose thinner. This gives a much harder and quicker curing finish than Rust Oleum alone. After two days it is fully fuel proof, gas or glow, with the hardner added.

I got as good a finish on this as some others I have finished with Auto paints at one tenth the work.
