I used a $22 kit from Advance Auto on my '95 Camry. I don't remember the brand, but it was in a foil pack. No drill or electric polisher needed, and it came with a sealer that they claim makes it permanent. It took about 20 minutes, start to finish, including reading the instructions. Results are outstanding. You could clean them up with a 2000 grit sandpaper (some came in the kit), but without the sealer they'll fog up again. I'll get another kit soon for my '01 Accord.
