Any suggestions on sanding blocks. I made a 4ft board for my horizontal stabilizer out of a straight 2x4. I'm having problems keeping the sandpaper on the board. I used contact cement and that's not seem to hold and when the edges peal up it digs into the foam. I'm at the start of a lot of sanding and I figure there's a LOT of experience out there with sanding. I could definitely use some suggestions. Thanks
