Imron is tough, and I always thought that urethanes were fuel resistant, but
I've recently seen airplanes painted with various urethanes, with gasoline
stains from the dyes in the 100 Low Lead gasoline we use. I have NOT seen
Imron with stains, but then again I haven't looked for stains on any planes
I know to have Imron on them. I just bought a new plane (new to me - it's a
restored 1940 Stearman) and the top wings have Imron on them. I'm going to
be careful not to spill.
But the urethanes don't seem to be softened or lifted or wrinkled by gas -
just stained.
