I have one of those for dry wall sanding and it works great. I never
thought about using it for the blaster! I can justify having it now! I
was moving it out of my way again for the umpteenth time last week. They
sell them at Home Depot and Lowes on sale about $20 for the samll two
gallon one. They had two sizes at the time I bought mine.
