my last car an Audi A6 had done over 90,000 miles and there were a few stone chips, a fact of life they are.
but i have only done 4K, it will be interesting to see if anybody else gets this problem, i know the bonnet is aluminium and this is always difficult to paint. when the car was 2 days old I Supagard'd it myself, as i have done many times in the past. since then i have waxed it with the Autoglym about 6 times, lost count to be honest, but i love to do it. the lines of the car are becomeing very seductive - ok i will stop right there.
if its just my car then i will take it on the chin and just say, bloody stone chips, lets see what transcribes.
