I finally found a local place that carries the "Black Beauty" copper slag. I suspect I will need to use medium for the most part. (paint, primer, rust) I was just looking for a second, third, etc. opinion.

Thanks

 

I'm not familiar with that abrasive and haven't used it. I use aluminum oxide for quick cutting of heavily rusted parts and glass bead for either a finish blast or just for a brighter end result. It is important to keep the air free of moisture and the abrasive sifted.

Yea, I thought about using aluminum oxide but the cost cannot be justified seeing how I will probably not recycle any media. I'll be doing pressurized blasting outside, k-member, rear-end, maybe even the full stripped down car.
