I sent an email request to the Van's builder support asking about the use of epoxy resin to glue the windows to the cabin. Ken Scott replied that they simply do not know if it will work or not , but that they do know that Weld-On 10 does work. I built a test sample by mixing west system epoxy and adding chopped fibers to get a texture that didn't sag under its own weight. I alcohol cleaned a strip of cabin top (it was trimmed away for the door) and a surplus strip of side window Plexiglas. Both strips had been scuffed thoroughly with 120 grit aluminum oxide. I used a liberal amount of epoxy to bond the 1 inch wide strips for a 6 inch overlap. Light pressure was applied with three clothespin type clamps. The piece cured for 24 hours at 70 degrees F and today I performed a test of the sheer strength of the joint. The junction of the epoxy and the Plexiglas failed when I applied some sharp raps with a light weight ball peen hammer. I don't have subjective quantitative values for the amount of force needed to break the joint, but the pieces came apart way too easily for me. The junction of the epoxy and cabin top didn't fail under extreme chisel torture. I'll do a similar test when i get my Plexiglas glue.

Did you do this same test using the Weld-on 10? I would be interested in
knowing how that one turns out.
