| There is a new product autoglym do which is perfect for the MINI's black paint.
Called Ultra Deep Shine.
It is the same kind of product as Super Resin Polish and does the same stuff, but really helps to enrich the deepness of the black colour and also prevents the hologram effect that can occur when using normal polishes that are not specifically for dark paint work.
I have a black cooper s and I swear by the Ultra Deep Shine now I have tried it.
Lock that shine in with Extra Gloss Protection and you will have one of the shiniest MINI's around.
p.s. always do as said above regarding 2 bucket method and using microfibre or wool wash mits rather than sponges. |
