My car has very little rust, and no undercoating, so I don't think I NEED a super abrasive media, but I certainly don't want to have problems with my paint job from left over Soda residual that I didn't wash off well enough.

How does glass bead compare to plastic bead? There's a shop in town that uses glass bead on cars, and they say they have good results. I have no experience with this shop though, so I'm trying to do my homework.
