Rated 4 out of 5 by from Works well. I bought this product to safely blast aluminum engine and brake parts. The ground glass works great at removing old paint, dirt and slight rust. Not the product to use on heavy rust or removing old powder coat. Working speed is medium to slow, but is safe, doesn't etch soft aluminum and left the parts looking almost too good to powder coat.

What would be the best media to remove rustoleum from the body of a 1992 Jeep Wrangler.

Asked by: Cjay
Aluminum oxide is very aggressive and would be able to strip most everything off a frame to bare metal the quickest

Which would be the best media for blasting light rust and some paint on inside of body, 10/40 or 40/70 ground glass?

Asked by: bcwood
40/70 will work well for the lighter rust but won't mar the surface as much as the rougher grit. The rougher 10/40 will work more quickly.
