resin or epoxy for transom

[Bigshrimpin]

Epoxy is great stuff . . . but I don't think it's the only resin that will work for your application. Your boat builder friend might be referring to a "GP" general purpose epoxy (hopefully not "GP" polyester). If your not doing work in close quarters (near neighbors), you can save quite a bit of money using iso-polyester over epoxy. I find that polyester wets out the fabric better and is generally easier to use than epoxy.
