It was still too easy to cut your self.

So I switched to a 3X12 in piece of 4mm foam. I too use WD40 and the whole strip can be cleaned in the sink with simple green or any spray degreaser. When it gets to funky toss it and cut another strip. A 9X12 in pad of 4mm foam is around a dollar.
I did go ahead and order some foam. I'll try it out when it arrives.
