I just started my second boat, a North Bay (from kit) yesterday afternoon. I coated the panel scarf joints with unthickened MAS exoxy, let it set a bit and then went back in with epoxy thickened with a bit of wood flour and cab-o-sil.

The MAS epoxy that came with the kit has the "slow" hardner. Even with garage temps in the low 60's, the epoxy seemed to be setting up awfully slow even by slow standards (and yes, I was careful to mix it VERY thoroughly). On my first boat, I used West Systems epoxy and even with cool garage temps, their slow hardner seemed to set up significantly faster than the MAS. I think that for bonding purposes at least, I may need to order some medium or fast different hardner...
