keep the glass cool while you work on it, if it overheats it cracks. use normal sandpaper for sanding it down but be careful, its VERY easy to fuck up and crack the glass. good luck!
biohazard Reviewed by biohazard on . Broken Bong = Steamroller So i broke my bong camping this weekend and plan on making a steamroller. The only thing is there is this edge the the bong broke that needs to be sanded down. Anyone ever sanded glass? What kind of sandpaper did you use? Any suggestions? Rating: 5
