I performed this repair on my Audi S4 wheels but methds would be identical for the silver MINI wheels so I thought I would post it here as well. I have an extra set of MINI wheels and did a colour test and was very satisfied with the results.
........................................
I had a couple damaged wheels on the S4. One had been curbed and one dropped on it's face on rough concrete and the clearcoat bunged up pretty bad on 3 of the spokes.
I prepped by sanding the clearcoat all the way off in spots and feathering smooth with 1500 and 2000 sandpaper. I filed on the curbed one as well. I painted last week with
this paint and this week I clearcoated it for protection. I didn't paint the whole wheel, I simply blended into the good areas.
It also works good just spraying into the lid and brushing on for small areas like edges that have been curbed.
I am absolutely thrilled with the results.
