Poorboy's SSR 1 & PwC are both great with light marring. I love the Sonus Paintwork Cleanser, but it may or may not have enough bite...I like to use it after the paint is perfect for a final vanity polish.
If you need to get more aggressive it is hard to go wrong with SSR 2.5.
Thanks for the responses guys! I had picked up some Menzerna FP since I had a $15 credit with Autopia. Sounds like it is a mild polish that might do the trick. I just wonder if it is too mild? The marring is very light and can only be seen with light at just the right angle. Menzerna FP seems to be fairly easy to use and the IP sounds like it is quite a bit more aggressive. I have been under the impression to start with the least aggressive and move up if you have to. What would be a good next step if the FP doesn't do the job?
You're correct to start-out with the least abrasive product that will delivered the results you're looking for.
As a noob with a PC, I started with FPII with a LC white pad, then tried IP with an orange LC pad without success. SSR2.5 with a yellow LC pad got the job done and I followed-up with FPII on a white LC pad and this gave me results that were far better than I had hoped for.
