As a mask for sandblasting glass rather deeply, I have been using 3M masking tape for years (#280-3511). But now they're discontinuing it
- Yikes! It's really thick paper with lots of goo, withstands nearly
1/4-inch of sandblasting with 100-grit silicon carbide before totally degrading, and never lifts during blasting but releases easily when wet. Two questions: Does anyone know where I can get some of this tape (3M doesn't have a clue)? and/or What is everyone else using?
