theres this 3M stuff for fiberglass boats that works wonders. search on Honda Tech for it. if that dosent work, then you might have to pay for them to redo it, but i think the 3m stuff will work
i checked out the 3M stuff and its just for buffing out the gelcoat, which will work but the oxidation will just come back quicker than if i had it painted with a clearcoat. i just think $250 is a little high for just the hood.
