The actual paint (the blue base coat) looks to be OK and the clear coat lifted when the gas got under it. You may be able to sand the bad clear and re-shoot clear on top. Cheap way is to get the clear coat spray can from H-D. This is a Lacquer and will look good but will not be as tough as an acrylic. Second choice is to stop at a body shop and see if they will respray the proper urethane clear coat. The tank would not have to be removed and everything could be taped off. I would guess $200-@300 going that route (best) and $15 going the rattle can clear route (just OK but will look good for a few years).

Let us know what you do and good luck from a guy that rode Goldwings for 20 years until I started falling asleep on them!


EDIT: didn't see the second page of picture showing the blue destroyed. H-D does have that color in a spray can. You can repair this without a tear down unless you desire a total paint job.

 

Man I have never seen fuel do that either. I'm thinking there was some fuel treatment or some other chemical that did that. I've gotten gas on all kinds of paint, even just regular rattle can primer and that has never happened.
Bum deal though no matter what brother.
