Sanding Guard for Inside Corners
Sanding inside corners used to leave nasty buzz marks from my sander banging into the adjacent face. I still haven’t tamed my sander, but now I get buzz-free results by protecting the adjacent face with a painter’s edging guide. It costs less than $2 at a home center and is so thin that I can sand virtually all the way into the corner. Now sander-base-whacking won’t leave marks.
