So I'm at my 3hp table grinder/belt sander just wailing away cutting a 1/8" steel plate, Sparks flying all over the place. Actually put on welding gloves because my hands were taking so much spark. Later I'm outside finishing up the job when I get a call. I can feel all these little bumps on my screen, they are metal flakes that landed on my turbo through the flap on my belt case. I mean the screen looked smeared with all these pocks. Wiped it over and over and low and behold, it all came off and left no sign of damage. This gorilla glass can take the heat!!
