I bought a nose protector but my glue job wasn't great. The protector used adhesive tape. Maybe the biggest problem is that the protector is on a rounded edge, but that's a whole other story. I think I could try two things:
1. put a thin layer of contact cement on the foam and board, press together, tape to hold it down while the contact cement
2. put a bead of silicon caulk between the foam and the board
I don't know if I'll ever want to remove the foam protector, but if I do, I don't know if the silicon caulk will take paint with it. I don't know if contact cement will take pain either for that matter.
