Repairing cracks in fiberglass gelcoat can be a challenge.  Sometimes there are so many of them that it is easier to go extreme and sand, grind, and recoat the entire surface.  Then it will be as good as new.

The spraying part of this video will be out next week. It’s already recorded, I just need to edit it (along with a dozen others on this Cheoy Lee project).

Hope you enjoy!!
