Bought a windshield for my utv, and it does not fit exactly right, so I need to grind off a little near the hinges, and maybe drill a new hole and move the hinge up a bit. It is a folding windshield. Can I use my right angle grinder to take a little off the edge, and how about using a high speed steel drill bit to drill a hole. Never worked with lexan, can someone advise me the proper way and tools?
