Hi folks. I bought a used S3 last October and it had a couple of stone chips where you could see the white primer. Last weekend (when it was finally warm enough !!!) I touched up the chips with Audi touch up paint. However, I only used the colour coat. The twin pack from Audi also contains a tin of laquer/clear coat. I'd always thought only metallics/pearls had a laquer coat on top, and that flat colours did not? So my question is, does my Imola yellow 8P S3 have a laquer/clear coat on top of the colour coat? Also, any suggestions for the best way to remove the stubborn bits of brake dust from my alloys - product and method? Thanks in advance for your help guys!
