: Greg - The problem may be more related to the epoxy than the glass. I had a
: similar problem using MAS fast hardener for making glue. It apparently
: cures before adequately penetrating the wood to be joined. I tried to
: fast-glue a laminated ash stem to the bow of a cedar stripped canoe. The
: next day, I tried the joint and it pulled right off with little effort.
: The fix was to remove the stem (it just popped off) and scrape and sand
: all of the cured epoxy down to bare wood. Re-gluing with a new batch of
: thickened epoxy after a preliminary soak with unthickened mix did the
: trick, but this time I used 75% MAS slow hardener with only 25% fast. It
: takes a couple of days to fully cure, but it works well.

John-The substrate was already sealed with two coats of epoxy, blush removed, sanded with 150 grit, when I put the glass down. The glass just peeled off, leaving a layer of epoxy which adhered to the panel with grip-of God tenacity. This problem seems to be one of glass-epoxy adhesion. I'll just have to go back to the drawing board, I guess.-Greg
