Paint Damage

That’s a good possibility as a lot of octane boosters use toluene. Could be he topped his tank off and added octane booster and some leaked out the vent or past the lid seal while driving.

What color would you repaint?

Good luck.

This is basic premium pump gas. I believe you are correct, that there was a cut in the paint from installing the Le Mons cap, and that allowed fluid to get up under it.

The only drain for the cap is the filler hole. I think I will drill a couple of holes for draining; both ion the cap assembly and in the body.

This is standard stock paint from BDR. Chevy calls is "Red Jewel".

I'll post some pictures when I get home later in the week.
