It is funny how we all say you need epoxy not poly for the SMC bottom yet I am looking at a gallon of resin that says
"SMC REPAIR"
"Ployester resin for repairing SMC and Fiberglass"...?

A good example of why we say use epoxy is this. I rebuilt my SN and it had a few major repairs made with poly. ten minutes with a screwdriver and all of the poly repairs had been removed. The poly resin peeled off the hull in sheets. Poly just doesn't bond well.

I use epoxy just because too but with the right prep work I never had a problem with poly before I switched and I only switched cause I was told to on here lol

Poly can be made to work but its never optimum.

Poly is ok for making new parts on a budget. Poly is not good for seconday bonds. Sometimes ot holds, sometimes it doesn't. Even with proper prep. I wouldn't use poly resin on any project that matters.

Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. The sheet is provided in rolls weighing up to 1000 kg.

Hahaha, just ran across this...

I believe it has something to do with the wax in the SMC. Kind of like you can't weld cast aluminum because of the release agents. You can use anything you want. It just depends on how long you want it to last.

Hmm That's interesting, Nomatter what you scratched it up with if it were "impregnated" with some type of wax anything would have trouble sticking. Interesting thought!
