Gasoline will mar almost all of today's off the shelf paint if not allowed to cure completely. Lustercote works well but needs a long cure time of several weeks. Most off the shelf enamel needs similar.

Used Lustercote on many projects with no issues involving multiple flying seasons. Major ones were a Nosen pink/white Citabria (glow) and Cub yellow cowl that housed a spitting G-62 gasser. Both were painted during warm weather and allowed to cure in the sun for over a week each.

I have seen some discoloration with certain colors of Lustercote during application. Cans had been stored in garage for some time. I now order fresh when I need it rather than leftover stored paint.

The issue I see with streaked or marred paint locally is lack of cure time. Just because it feels dry, it isn't. I use the fingernail test. If you can leave a dent with your fingernail it isn't cured. Most enamel/urethane paint is hard once cured. Feel the painted parts on your new ARF and you will see what I mean.
