Thanks. That's great advice. So can I substitute the 403 microfiber mixed with the polyester resin for the Marine-Tex?West System 403 "microfibers" can be added; however, if you open the container in a wind, the contests can disappear before your eyes!
The patches aren't pretty, but I wouldn't spend the time it takes to "beautify" them. Otherwise, wait for the off-season to do (or re-do) fiberglass repairs.
The patch at the bow is probably worth keeping "as-is", as it's over-done and at a natural collision point. (Meaning, it may need "re-addressing" after misadventure). A pressurized leak test would help in that decision.
The dents should be drilled to smoothness at the edges. That's "The Ideal" for Marine-Tex. Other places should be heavily scored before using Marine-Tex. Lay a heavy clear plastic film over the repair, and gently spread the Marine-Tex to desired smoothness. Afterwards, further treatment may not be necessary.
To maximize Marine-Tex' gripping power, I'd use a Harbor Freight grinder ($9) on each of the larger repairs. (The 4-inch wheel has to be purchased separately).
I don't see why not, although I use epoxy exclusively. Googled:Thanks. That's great advice. So can I substitute the 403 microfiber mixed with the polyester resin for the Marine-Tex?
One more question. In regards to the polyester resin is there any advantage of finishing with PVA vs wax? Ok, one more questionI don't see why not, although I use epoxy exclusively. Googled:

Don’t forget the trick of smoothing plastic like visqueen, merchandise bag sections or even plastic wrap if that’s all you have... on top of the marine Tex repair. you’ll be pleasantly surprised at how smooth it comes out with no sanding required.1st crack at fiberglassing. I've been following po-man's fiberglass thread/adventure and wanted to throw some pics up to see if Marine-Tex will work for these repairs. The previous patches seem solid, should I grind these back to see what's underneath? Thanks for the advice.
Wow, the saran wrap trick really does the trick. I've trapped some air bubbles, but I'm just pleased to reestablish the bow line.Don’t forget the trick of smoothing plastic like visqueen, merchandise bag sections or even plastic wrap if that’s all you have... on top of the marine Tex repair. you’ll be pleasantly surprised at how smooth it comes out with no sanding required.
