So Ive got a little secret project going on and I need some advice on cutting urethane. Would a dremel work or would it just melt it as it was cutting? I also have read where people just used a utility knife but I feel that would take forever. Has anyone cut/trimmed bumpers or skirts with good results?

I used it Plenty of times at work and home..As Long as you are using the Cutting wheel for the Dremel ..You will be fine! Never used it with a Grinding Wheel or Stone...Just make sure you Measure twice and cut once :)

An air powered body saw would probably be the best tool for the job. I've made small cuts by hand with a hacksaw or even just a sawzall blade though.

A dremel or air grinder will work great. Different bits for different levels of precision you want, smaller bits like 1/16" don't grab much so they're easy to control. What I did for the JDM fog cutouts on my Civic was use a drywall bit, actually. Obviously not very precise, but for roughing out it worked great.

EDIT: Just in case you're curious, this is the drywall bit I'm talking about.

So do you just drill through then pull it along the line you want to cut?

I would just use an air/reciprocating saw to get it close and then a file and sand paper to get it perfect.
