Any suggestions on what type, and where to buy from?

I'm cutting sanding sheets for my bar sander.

I use the 3m sprays - sometimes I use 3M77, other times I use the repositionable stuff - forgot what number that is.

Both hold the andpaper really well - the biggest issue is getting the paper off when you want to replace it - which is why I started experimenting with the respoitionable stuff. Works well so far.

IMHO there is nothing better than the good ol double sided tape for attaching sandpaper to blocks.

I usually leave a "tag" at each end that I can get my thumbnail under to remove when the paper has worn out.

Never had it let go yet...

I use double sided tape too. The 3M 77 spray works well, but that stuff is wickedly dangerous. Do not breath it. Huge cancer causing stuff. I know a lot of people who will not get close to it even if it is not in use. (I have sheeted many a wing with it, probably going to die now).
