Sometimes we have to gouge out some of the foam on the edge of a glassed surface, in order to put in flox before laying glass over that edge. I have always done this using a razor knife or a pointed stick or....
I found a very easy way if you have a Dremel. Oh, if you don't have a Dremel that is another tip, get one. Use a small abrasive bit to do the gouging. It is fast and really cleans the foam down to the surface of the glass so the flox will be able to get a good bond. Finishing the ailerons so I can paint the wings over the Thanksgiving weekend.
