Yep, Yellowtudor, when I worked for West Marine we had a guy who built kayaks, and actually held classes where people could build their own while taking the course. He bought it in 55 gallon drums. There was one of the West System epoxies he liked for the same transparency reason you mention, to let the wood show through, and it wouldn't yellow.

Johnboy: Glad that helped. I asked Dan where he bought his, and he didn't remember, other than it was online. He said he got like 200 of them for something over a hundred bucks. He bought 1/8 and 3/16, and feels the 1/8 size is more than sufficient for most jobs, and the 3/16 are kind of overkill for tin work and stuff like that. I googled cleco, and a bunch of sources came up.
