That must SUUUUUUUCK to spend all that time, only for the grips to crack or get a hole. I’ve often wondered (more so earlier in my polishing career) “what if I mess this thing up”, after spending the dough on the gun,then all of the hours. It’s why I prefer slower methods vs super abrasive/aggressive wheels, etc. I have seen pics of the rounded corners and waves in the metal from guys that want to rush.
