Well I am starting my own threat for some wisdom, I'm a big lurker but for some reason I couldn't find to much. I'm trying to bring back the shine to my old supra. I removed the cover snaps in the fiberglass and 90% of them have spider cracks and at least 10 of them have chunks out of the gel coat.
It doesn't appear that who ever installed the snaps chamfered the holes and that is what is causing the spider cracks. IDIOTS!!!! so now I need to deal with this problem before it gets worse. The plate that obscures the hole for tower lighting was drilled correctly, which makes me think that the snap cover wasn't factory installed.
Think I could use that in a low speed drill going counter clockwise to not catch the start of chip that is already there? In my line of work when we have cracks in steel we drill the end of the crack so it doesn't continue, could I do the same to the layer of the gelcoat? What about sealing up everything? Would some 4200 work? Thanks in adv guys!
