I bought an Angle Grinder and Grit Flap Discs to remove paint on my MV in order to take off a few coats of paint before repainting, as I prefer to do this rather than use paint stripper. As I'll be wearing coveralls, gloves, eye protection and a mask, I'm wondering if it is in order to remove the guard on the Grinder, so that all of the disc can be in contact with the paint rather than just half. I appreciate that a guard is needed for more serious work such as cutting with a grindstone, but would it matter to remove the guard with a Grit Flap Disc?
