What would be the best product to use on the door pillars that have a matt black vinyl type covering on the outside? these seem to show water marks etc. Really want something to remove these marks/stains and make them clean, but keep the same sheen they have now if that makes sense.
Thanks
You can clean/protect them in the exact same way you would paint, so any polish/wax/sealant. Personally on matt black trim I like to use Aerospace 303 protectant
