Has anyone ever used coal slag media to blast fiberglass parts?

I need to strip some spoiler pieces and a hood scoop. Anyone have any experience using coal slag media on their fiberglass pieces.

I personally would never blast 'glass parts. They are too soft for that. It will probably blast away the surface of the glass, making it thinner and wavy.

I was thinking that too. I've blasted plastic parts and rubber parts as well with no issues in the past though.
Very carefully..use a low pressure and a fine grit like 80/100 to blast with..can be done but the pressure used on metal parts will blast glass to nothing in a heartbeat..
