: I agree that the glue itself is difficult to remove.
: One trick that I learned from David @ altakayak is to make a curved
: scraper (think Ulu knife) from a scrap of Lexan or plexi (a few
: seconds on the disc sander), and use that to remove glued-on
: foam when necessary. If you've careful you can get the foam off
: (mostly) intact, without scraping the (fiberglass) surface.

Once you get the foam off, lacquer thinner will remove the glue without damaging the surface.
