ORIGINAL: buzzard bait
There is a big difference between cold raw fuel and hot exhaust. I had disastrous results with a Rustoleum finish on a Stick 40 Plus - the plans actually recommended it. It cured for at least two weeks, and in a test with cold fuel it seemed fine. But in a few weeks of flying the paint downstream from the exhaust, all the way back to the tail, turned into a gooey, oil-soaked mess. Jim
I agree with buzz bait, I had rotten luck with Rustoleum clear on my cowl. It started getting all gooey around the exhaust and just continued to work its way around the sides. I will never use it again, and this was after letting is cure for 2+ weeks.
