Patching Gelcoat

[Black_Fly]

I’m wondering if thickened Gflex is good for patching gouges in Gelcoat boats. The soapy, crumbly nature of the coating is what concerns me.

Most of us use thickened epoxy for that type of repair. Gflex should do the trick.
A quick search of this site finds many such threads about repair gel coat and scratches. You should be able to find all you need to know:

Added some green flakes. Seems like it will hold.
