Funny thing is, I was acutally looking at those the other day in the local paint shop.

My guys had one (Run Razor) in our paint shop. I have the same problem, but won't be able to get to it for a week or so. I'll let you know how it works if you can wait that long.

On the other hand, they are only about $8.

If you try to take it all in one slice, you'll make a mess- one chattered cut. If you take small slices and keep putting a fresh blade in, especially for the final cuts, you'll take it right off.
