Unknown spots on glass and the 7424XP

[rh2469]

The title says it all, I have been dealing with some spots on the glass of my car, pics below. The spots were there when I purchased the car and were also on the paint. I have been able to get the majority of the spots off the paint but have been struggling getting them off the glass. The best and most effective way of removing the spots is with rubbing compound and a TON, I mean a TON of elbow grease. So, as I sit here waiting for my Porter Cable 7424XP to be delivered, I want to know. Has anyone taken the 7424 to glass? I believe it will increase the effectiveness of the rubbing compound and help my back survive to detail yet another day. Give me your thoughts.

Did you clay your glass first?

Hey Chris; Yes I did clay the glass. I purchased the clay for that very reason and it would not remove the spots. I have tried every half-*** product I could find and several methods off the Internet. The only one that half works is the rubbing compound. The spots are lite very hard to see but when water hits them they are easier to see, so they are not gone, just lightened up a bit.

Have you tried a razor blade?

The PC will probably help, but the focus pads on a drill may be a better solution. This mustang at Hot August Nights was suffering from much of the same issue... they had tried EVERYTHING to get the spots off. We started with clay and it didn't do a thing. Went to the yellow 4" + shr on the drill and with just a few minutes of work it cleared the glass right up!!
