I am looking to buy the Harbor Freight rotary soon and was wondering what some good polishes to use with it are. My trucks finish is in fairly good shape other than the rocker panels (wide tires outside the flares tend to do a number on the lower door panels). Anyway, I was thinking stuff like menzerna IP, SSR2.5, #80 and #83 would be good? Anything else I should look into? I will need something that can take out some wetsanding work as well.
