resin or epoxy for transom

[bigeasy1]

As bigshrimpin stated,maybe he meant general purpose epoxy resin.I've used System Three General purpose epoxy resin on three transoms,and it performed flawlessly.
Also as stated,a polyester or vinylester resin can be used to do the remaining glass layup at a lesser cost than epoxy.
They will wet out many types of material far easier than epoxy.

I did the transom on my 23 Tsunami with epoxy to laminate the plywood core,and layed up the interior skin and stringer tie ins with 1708 fabric and polyester resin.
I've also used the gel magic by system three,and as island said,it works super,although i think it's kind of pricey to use on a transom.
