old mag wheels that have not been well-cleaned.
There was a layer of gunk on the wheel that i couldn't get rid of.
I've tired P21s Gel on my GF's bimmer wheels.. and it didn't get the brake dust specks off.. (10 months ago)
Klasse didn't either.. ( last month)
then i tired Nu-finsih on them.. (just now)
it looked as good as new..
maybe because Nu-finish is uses such strong chemicals ? ( it really smells)
