That is a problem with the car, I bought it with about 60 miles on the clock and it had been washed twice by the dealer, swirl marks galore!! It's not that bad really, but they are there and the cleaner it is the more they stand out! I'll be looking at getting it PC'd before the summers out. Just worried about doing more harm than good!
I only have the driveway to clean it on at home, but my Dad owns a repair shop so weekends I can usually get to clean it inside!
On a side note my Dad has an expensive orbital polisher but he seems to think it would be too abbrasive for use with polishes. I trust what he tells me, but I'm not sure how uptodate he is with newer products!
Oh yeah, Rich were your photos taken with your 350d?
