Hey guys I am new to this whole thing but have been reading quite a bit on the topic. From what I have read, the best way to remove swirl marks is to use a rotary buffer with a good polish and pad combination. My question is if there is a product/way to remove the light swirl marks which were made last time i washed the car (wool mitt went bad on me and i didnt use 2 buckets like i usually do) by hand. I understand that it will probably take a while and be a pain in the ass, but i want to try it by hand before i invest in a porter cable. Would something like scratchX, applied 3-4 times sufficiently do the job? I am also looking at 3M ultrafina however that is what i would use with a rotary buffer.
