You can get good epoxies to stick, no problem. You just have to clean with acetone, sand and clean again with acetone to make sure you get rid of any blush and get enough tooth fro the epoxy to stick - 80 grit paper is what I've used with Hysol and it stayed until the end...
Correct, you have to make a "mechanical" bond. basically have a rough surface to attach, with little to no resin residue.
You guys remember Stabilit? the glue that Yellow Aircraft used to sell for use on their kits? Man that sure smelled strong.
