I'm currently looking to buy a Metallic Black M3. The car is in excellent condition except the previous owner(s) have obviously taken it through the car wash a few times and you can see the brush marks.
On my previous cars I've used t-Cut colour Magic (matched to the car colour) but this metallic black seems to have a slight blue in it when close up??
Can anybody recommend a good product/method for removing these brush marks please?
