I have an 8V S3 in sepang blue which was coated with Gtechniq C1 and Exo when I bought it, both these were applied in 2015. What I have noticed over the last few days with the increased number of bird poo hits is that the paint seems to suffer from etching very easily. Today I wiped off one which must have been on the car for less than two hours and I can see a mark left on the clearcoat where it had been. Is this typical of audi paint as I can`t remember the same problem with other cars I have owned? What advice can anyone give on products to try that might help this out, can take off the poop without scratching the paint so it is just the etch mark that is left that`s the main problem. I have a DA polisher but if I use that then it will no doubt remove any C1 that is left, would a good detail and then layer up with wax etc be a better option ? Thanks for any tips or advice anyone can supply.
