I used a saw on mine, but i think if i had to do over, several passes with a razor blade would be the ticket.
x2Mouse said:I marked my cut ahead of time with a white grease pencil, measuring my cut (1 inch) along the entire flare. I used a jig saw with a fine metal blade in order to keep good control of the cut (I don't have good control free-handing with a utility knife). I have cut two full sets with this method and like the results.
Also, I prefer to cut only the minimum required, as it retains the stock appearance better with less cut away.
