I removed as many components as possible. Only thing that was left on there were the headset and cranks. I just masked it off with painters tape. I used aircraft stripper in aerosol form like THIS. Sprayed it liberally all over and let it sit for 10 minutes. Used 400 grit sand paper to remove excess clear coat and decals. I had to do this a few times to strip the frame completely. Then, I used 800 grit and wetsanded the frame and finally used Mothers aluminum polish to give it a nice finish.

The DP18 was done using the same process except I used "Eazy Off Oven cleaner" instead of the aircraft stripper.

I may clear coat it in the future but I'm simply too lazy right now.
