I bought a cutting wheel designed for plastic when I did my quad tip mod. I put blue painters tape on the painted side to reduce the chances of the paint flaking. I used a small diameter stone on the dremel to cut the slots/holes.
I will admit, it took some courage to start cutting a perfectly good bumper. Mechanical work I can handle, but body work scares me.

Jazzman, about 14 years ago, I had a 1986 Olds 442. I was a member of a G-body forum (oldspower.com I think) and ended up selling my car. I remember a member on one of the forums with the name Jazzman. Was that you? Here's my old car. I wish I still had it.

Guys, I used a retractable razor knife. I started out using a jig saw but that required a lot of clean up and wasn't cutting as clean a cut as I wanted. A new blade and a slow steady hand left beautiful cuts that needed no clean up and very accurate cuts. Just take your time and move the blade slowly and you'll be done with the cut and clean up sooner than using a body saw, jigsaw, etc.
Did you basically score all along the cut line and then keep going over it until you got all the way through, or did you basically work it like a saw, slow and steady from one end to the other?

I slowly pushed it thru the urethane to the factory cut line you'll see when you have the bumper cover off. Once on the line, I just slowly pulled it towards me with constant pressure just like you were cutting thru a brick of cheese. Too fast and the blade could jump and cut unwanted areas. If I went too slow, I wouldn't be cutting much at all. As was said, just use a new blade. It took all of 5 minutes to do the job. There are also cuts that need to be made for the tabs to go thru. I just used a drill on both ends of the hole area and then applied sideways pressure on the drill bits to cut the slot. The urethane is pretty soft.

Thanks man. I'm left feeling A) a little dumb for not thinking of this, since I always have a utility knife and fresh blades in the toolbox and keep it handy anytime I'm doing anything at all, and B) thankful that I can now spend money I was going to spend on tools to do this job, on more mods.
