If they are original, I would not even think of removing them. My front letters were already riveted in place, so I just drilled them out and polished the smooth surface. On the rear letters under the rear window (which were held in place with the original rear mounts) a 4" diameter circular buffing cloth designed to be used with a drill was purchased. I picked the buffing tool up at O'Reilly's Auto Parts. It is comprised of about 20 layers of duck cloth loosely stitched together. I purchased the thinnest one I could find (there were several thicknesses from which to choose) and was able to do an acceptable job with the drill. I also tried a 2", a 3", and a 6" diameter, but the 4" worked best. In all honesty, from 5' out you cannot even notice anything between the letters the cyclo cannot get to. I would hesitate to use a buffer too close the the letters for fear that the rear mounts would shear if the wool bonnet bumped a letter in the wrong place.
The cloth becomes "flexible" when pushed against the surface radially. A very slow speed works best.
The circular cloth buffing tools were also used on various places on the LPG tanks. The Propane/Butane tanks had a lot of deep scratches. I wet sanded them with 120, 220, and 400 grit, then compounded with F-9, F-7, and C. S was used with the cyclo on areas I could get to.
For the most part I found that compounding with S was a waste of time, as the 7" wool bonnets were unable to finish the surface with anything beyond "C" grade Nuvite. Wool bonnets, in my experience, always left a "3-D Hologram" which had to be removed with a cyclo.
