I need to get the courage up I guess.Just cut mine 3 days ago.Took out 2". Piece of cake! Got the info from here (this forum). Very helpful! Thank you guys. Just use a lot of masking tape and very fine sand paper. After you are done use MEK from your local hardware store to seal the edge. Looks like factory cut. I was using a jigsaw with a metal blade (blade with fine teeth).
