I have a Carl Goldberg Bucker that I covered with Monokote and painted with LusterKote in 1995 and it still looks great. The paint adheard well with no peeling. I used 400 grit sand paper to
lightly scuff the surface and then cleaned with acetone and taped off using 3M fine line tape. I have done several planes like this with no problems. I am finishing up a 1/5 Pica Waco covered with Solartex and I am going to use Rusteolum Pro to paint it and Rusteolum Pro Clear. I have read alot of posts from members who have used it with good results.I painted a sample and put gasolene on it and it held up with no problems. I have heard some say it is not fuel proof using nitro.
