OK, I relaize that this question has probably been asked many times before but I don't know if anything new has come out on the market.
I have a number of small (some of them you ahve to be looking at just the right angle to see) scratches. some are slightly larger but still inconspicuous until you are right up along side the car.
What have you guys had good luck with and are there any special tips or techniques?
Your towels may be causing the scratches, even if you use cotton towels the stitching is poly thread. You can use 3M Scratch and Swirl Remover to get them out, if your a Zaino user a few coats of Z-5 should take care of your problem. :)
Make sure you are using a cotton mitt or wrapped sponge. Like carl said the towels are a big thing, I remember actually seeing the swirls get on my paint from the towel I was using. :(
