All,
Researching the
repair of crazing, a.k.a. spider cracks in
gelcoat in this forum yields the same results as other on-line sources; fill and
paint or buff. Few address the underlying problem that the
fiberglass is flexing. I've seen on my
boat the return of cracks and a long-time marina owner confirmed my observation that the cracks usually do return. My common engineering sense tells me that the only reasonable way to fix the problem would be to fill with a flexible filler and
paint with a flexible paint. Of course, the flexible paint will not have the durability of a hard
epoxy paint. Also, there is the challenge of applying a filler to the cracks that are so thin that the task of grinding them wider is necessary.
I'm thinking of using a flexible
epoxy thinned down to
water consistency, if a product can be found, with a one-part paint over top.
Any comments, suggestions?
