Don't really know how these occurred but they need repaired. I was thinking Bondo fiberglass resin with a little cloth in the bigger gash and then sanded and flowcoat to match. Its white and on the bottom so the color won't have to be perfect. The one that is below the gun wale may be a little different but I think my new decal will cover once it's repaired.

There is a product called Tiger Hair. Reminds me of bondo with glass in it all ready to go catalize spread sand then finish. It's for doing small cosmetic repairs in fiberglass just like the pics posted.

take it to chris at classic fiberglass an he will make it look new.

Not that Chris won't do a great job, but I'm trying to fix it myself. Unless it's a HUGE job, I'm going to do whatever I can with my own two hands...

Have you looked into MarineTex?

Yes, I'm just a little leery of finishing with flowcoat on top of it since Marinetex is epoxy based. Poly coatings and epoxy don't really go well together. I know you can sand and clean them and get them to bond, I just don't know if I trust it below waterline.

Why are you wanting to use Flowcoat?

Marine tex is white. Patch area with it sand it buff it. Good as new.

I've actually got some for some other minor repairs. I wanted to use it because it's somewhat easier to use than gelcoat since it has wax in it and sets hard vs adding wax or pva or covering any gelcoat to set.
Does Marinetex come to a gloss like a gelcoated finish?

Properly prep it/rough it up then clean with acetone. Use Marintex and get some wax paper to cover while curing. Then wet-sand and buff. There some videos on YT. Post some pics when you're done.

This was my thread from wet sanding the boat. It has pics of it complete after all damage was repaired. The pic of the passenger side of the boat shows the area at the corner of the sponson that was repaired. Can't see it at all. Blended in perfectly. All of the spots did.
