West systems epoxy have fallen behind the times. Lots of blush, yellowing, secondary bonding issues, hard ratio to mix accurately, but granted not much of an issue in the OP's requirements
My Favorite epoxy is System3, the SB112 and Clearcoat resins for laminating fiberglass cloth onto wood. Have not tried their new silvertip resin.
They have various rot fix products too.
http://www.systemthree.com/store/pc/Rot-Repair-c33.htmTheir clear coat resin is pretty thin stuff, and cures very slow, Good for when a bunch of epoxy cures in a thick mass.
Epoxy creates its own heat so if a large mass is to cure, it can generate too much heat and expand, then shrink afterwards and compromise the bond.
