Well after reading many forums regarding what paint does what, goes over what, is resistant to what . . . I still made a big mistake!
I finished my TT with Rustoleum spray enamel, good so far. When I went to buy some clear, they didn't have any. I was told that Painters Touch by Rustoleum was "compatible". No it is not, (Not in the ways we need anyway) I can guarantee that. I now have a slight orange peel look where the water based Painters Touch upset the enamel. Also, I've learned (from the school of hard knocks) that Painters Touch is not fuel proof, nor fuel resistant; well maybe somewhat fuel "resistant". I now have to clean the plane as best I can and reshoot some clear.
Oh well, it's a fun hobby no matter.
