I tried it on my wife's Octavia where some scummy scrote had keyed it down to the undercoat and the chip stick that comes with it actually did a surprisingly good job on the scratch. Because black cars are famous for showing every tiny scratch and blemish, we developed this triple-action black car polish to remove contaminants, polish away scratches and build up a deep shine. All applications are assessed individually by Klarna and decisions are based on individual circumstances. The colour magic brand is some thing that I have used before so I knew what to expect, I always find it works best applying Several coats to the scratched area and then polishing the whole Panel and using an electric polisher makes it a lot easier .I think its given then that colour charged waxes do change the surface colour to some extent, and will do moreso onn white areas where chips have gone through. I agree with you though, maybe myself and others are slightly hooked on brand names, which may produce the same results of lesser names.

I found that your had to really rub on the wax chip stick overlapping onto the paint slightly until you had built the level up so it was flush with the surrounding paint.
