Welding Spots

How would you go about removing welding spots from a window. I have an opportunity to repair three 3x3.5ft windows all have welding spots over them. Some of the spots have the metal debris and some have pits where the metal debris was chipped off. Will the lodged metal debris scratch the glass as I sand or will it just grind away scratch free? I appreciate your thoughts, thanks.

PASS!!!. Welding splater pits pretty deep. and usually all over. You will be grinding away so much material i really dont think in a window that small you would get distortion free. you can always try one but i think its cheaper to replace


Talk to Cody or Cole. They told me it can be done w/ the GR system.
