How to look after your paintwork
I’d agree with MarcoPolo, took me three cleanings to get mine sorted the first time I did them. That looks like a lot of purple on the first cleaning, so I’ll bet it didnt all come out.
E87 118d, stock, plus PDC control unit drain, Parrot, debadged, Mothercare baby shades (but no babies), and occassionally a good layer of wax. Instantly forgettable, and thats the way I like it.
Good idea, I'll hit them again before buying more products. In regards to the large amount of purple on the first clean, that's because the instructions say to put on a dry wheel, not pre washed. Spraying the products on loose dust was such a waste of product so on the other wheels I wiped them with a damp rag first. Much less purple.
