why stop halfway?

to put a Watercraft factory top deck on in the future. :Banane01:

butti's 24/7 ski (camo boat) has a reinforced bondline ONLY...all the work was supposedly done at wammers....he got the hull from Ed3SJ

ok, that was Tim Scott's old SJ before he got his current wammer hull.

Remember not to get it too thick, heat will build up in the resin and it will crack.

Newer SJ's like yours also have SMC bottom deck so epoxy resin is best for adhesion...has anyone had fiberglass resin hold on SMC for as long as this thread is old ?

ALL SJ's have SMC bottom decks. :clown:

you can add pigment if you want to... you only need a couple drops.

we use pretty much fiberglass resin here.....IMO epoxy is overkill


on my fx we used 1 layer 17 oz biax, then still have the c/k to add on....


with bill's 24/7 ski we used 2 layers of 17 per side, plus some other selective reinforcement with chopper glass....all done with FG resin

I bought the 24/7 ski in the above post. if it only had polyester resin it held up fine. I beat the hell out of it fore a few years and the reinforcement never delaminated from the SMC. That said, it must have been preped very well and the adhesion was more mechanical than chemical.


knowing that, I'd still use epoxy resin for future projects.

Secondary bonding always relies on a mechanical linking to a surface or cured material. Chemical linking occurs in the original building and curing of a part (primary bonding). Once that cures all bonding is secondary.

That's why we use epoxy because it has the best secondary bonding adhesion. But as always, proper surface preparation is always important.

ok got some 4-2-1 and micro ballons do i get my resin then mix in the baloons then add hardener or mix resin and hardener then ballons or does it not matter
