I am working on emp fairings for my rv10. I decided I wanted more grip for the blind rivets so put .025 strip of aluminum about .5" tall along the fairings. I used west 406 with the west 105 and 206 hardener. When I was final drilling the holes on the emp (originally just drilled to 3/32 then final to #30) the strip of aluminum just came right off.
I scuffed the strips with 120 grit sandpaper along with the fiberglass and cleaned both with acetone before using my mayonaise consistancy mixture of epoxy and 406. The epoxy didn't bond all to the aluminum. Any suggestions what went wrong?
