51Deluxe, you could probably be right. I don't know how it was prepped or painted since I didn't do it and it was done before I ever worked there. When the guy brought the car in though, the hood was BURNING hot to where you couldn't barely touch it without burning yourself. I figured that since it got so hot that it reacted underneath the paint and since it's fiberglass and not metal, it made it bubble like that.
