whats the best stuff to make the plastic stips and black parts of the doors and bumpers 'blacker' if that makes sense?
also i gave my wheels the once over with 'wonder wheels' but didnt put anything on them afterwards, there caked in brake dust yet again... so is there something i should be putting on them afterwards i.e. wax? if so whats good? and should i expect large amounts of brake dust to be on the wheels even such a short amount of time after a full clean?
I tried searching for this stuff but i think im a bit special with the search button, or it doesnt agree with me.
