ChristopherO, appreciate the feedback about the color. It's true that our epoxies don't cure translucent. (Light coloring, but definitely visible.) That's deliberate because in most adhesive applications, if you don't mix the two components well, you weaken the bond. The different colors of the component -- and the new color of the mixed components -- helps you visually insure that you're getting the strongest bond. And, in most applications, you don't see the cured adhesive as it's covered by the materials.
Totally understand your point here about laminating and letting the beauty of the wood shine through. A thought: maybe consider different adhesives for exterior lamination versus structural assembly.
As I wrote at the beginning, this is a new potential use for our adhesives, so I'm learning, and grateful for that. Clear curing is possible, but we haven't focused on that property to date. We've focused on strength and flexibility (for E5) not visual appeal, but we've done clear before, too.
