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.

That is a stroke of genius. Never even occurred to me given the scale involved, but I could see it working as long as the blade is fresh and sharp. Hell with finding new tools, trying this first for sure.

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.

I feel the same way, since it took me about 3 hours with a dremel.

Sucker.

The one advantage Winnipeg has over California: 60% of the year to plan and strategize for your mods to finally see the light of day. Disadvantage: 60% of the year you can either drive your car and watch it rot in real time, or not drive it at all.
