Re: Help with sanding after media blasting.

I have used crushed glass to blast almost all of the sheet metal and other parts on my truck. It is a little slower than some of the other medias but it doesn't damage sheet metal and it leaves such a nice surface that it is well worth it. All I do is wipe it down while blowing with air and it is ready to epoxy prime. The primer lays down very smooth. I use a good 1:1 epoxy.
