Next weekend I plan on doing my winter prep job on the Lexus. My plan is 205 w/orange and maybe finish down a little with 205 on black/grey pad. You guys have taught me so well that I have very little marring since the Spring prep I did. Since I don't need to use anything harsh, like 105, do I still need to tape the car up before polishing? There is very little rubber on an IS and I thought I have seen several folks using 205 for cetain plastics and chrome. I plan to follow up with some Prep Wash to help the nooks and crannys. Any thoughts? Will I hurt anything?
