Silicone beads provide no-slip surface
I can't see through the blade guard on my mitersaw, so to get accurate cuts, I have to lift it up, pull the blade down to the workpiece, and nudge the workpiece until the cut mark aligns with the blade. To simplify this process, apply beads of silicone an inch apart on the front of the blade guard, as shown. This gives your thumb enough traction on the slick surface to lift the guard while pulling the blade down with your right hand—freeing up your left hand to make precise adjustments.
