I just trimmed down my rear hugger last night (I was inspired by this thread!) I used a 4 1/2 inch angle grinder, a file, and some fine sand paper for the job and it came out looking really nice. I also masked with tape, then cut with a cutoff wheel on the grinder. I then switched a grinding wheel to get the shape and bevel perfect, used the file for the tight spots, and sand paper for a smooth finish. The grinder worked great - very fast and no melting problems. The whole job took me about half an hour. I think tonight I might revise the shape a little (If only because that grinder is so fun to use!). Digi camera is coming soon, so maybe I can get some pics.
