I've used Rustoleum for years with no problems. But, I switched to Nelson's a couple of years ago for two reasons. One, the Rustoleum spray pattern was just too small for large planes. Two, Nelson's paint dries almost instantly. No cureing time. Nelson's is excellent paint, but very sensitive to spray pressures. (Search the threads). Also, beware. Nelson's paint does not dry to a high gloss like Rustoleum. But, after about an hour you can sand it like a hard shelled primer. Almost never runs, but if it does let it dry about an hour and it sands out smooth as glass. Also, Nelson's can be spot patched and will blend into the base coat like no other paint I've ever seen. Can't do any of that with Rustoleum.
