Probably some type of chisel Dube, just be careful. I had the guy at the body shop re-do my front rain gutter with some stuff he suggested (and it has held up perfect so far), but he filled it so much that when I recently went to add chrome gutter trim, it would not go on. Just something to think about, a lot of people will never use that trim, but after seeing it, I thought it would look good on my truck, and it would have if I could have got it on. Oh well, live and learn! Good luck!
