I have something here in my shop that I use almost everyday for other purposes that might work but would definitely need testing. It is basically liquid latex rubber sold in art supply and hobby stores as frisket material. I use it for paint masking on the control panels I build when there is an odd shape to mask and would be a pain to try to mask with tape. I'm sure it would need multiple coats and even then blasting may take it right off. Like I say, needs testing.LatakiaLover wrote:Tape idea v2.0: There must be some substance that's between rubber cement and thickened epoxy in blast resistance that can be built up in layers/coats, or even applied in a single layer of user-controlled varying thickness. Preferably soluble with something easy, cheap, and safe.
Also there are some pretty creative materials out there being used by shops doing blast etching on glass. I've used monument blasting tape but I would not consider it suitable for any of the work we do on pipes. It is too heavy and really made for flat surfaces. I think the glass blasters have a liquid material of some sort too.
That's my nickels worth.
