That would have been my suggestion. WD-40 is good for anything. It'll grow hair too. Great in Chili.
If something needs fixin' the answer is either duct tape or WD-40. I didn't think the duct tape would work. :)
I spray it on my Norelco's shaving heads before shaving. It's better than any preshave lotion, it makes the shaver just glide over your face.
