I have a 1966 fiberglass nose bowl that has "spiderweb" looking cracks in the gelcoat. A couple years ago (about 200hrs) I sanded it down and sprayed a filler coat and repainted- only to have them show up again. Is there a longer lasting way to take care of this problem of cracking? It's a certified airplane and new cowls aren't an option, so I have to deal with repair. The cracks are not structural, bit cosmetic only.
Thanks,
