Noob question, never waxed polished a car before and this was my first attemp. After reading a lot of the threads here looking for advice I clayed and used Colorx on a section of my car where the paint has started to oxidize. The results were much better than I had expected since it was quite dull and a large area. Problem is that I picked up some water from around the gas lid area when applying and I think this is what created some noticeable swirl marks. So how long does ColorX last until the dullness is back and if I wanted to remove it to try again to eliminate the swirl marks what would I use/do? Clayed & used Meguiars Gold on the rest of the car and it turned out great so it wasn't a total failure.
