    I wonder if those of you with experience in sand/slurry/soda blasting can share any tips on masking/covering/protecting areas.

    From what I understand rubbery materials are best in order to "bounce" grit/shot off, for smaller grit and stencil work I noticed a lot of people use vinyl tape ranging from 0.2-0.4mm but what about larger grit/shot and more heavy duty blasting?

    For my current project I'm contemplating using rubber hoses for railing/tubes/pipes and for larger items air tubes from car/bicycle tires along with vinyl tape.

    What do you guys use when you have mirror finish stainless welded to structures that need to be blasted?

    Sheet rubber, sold as swimming pool/garden pool liner. About 70 cents a square foot.
