Applied Waxoyl to black SRT6 exterior using Aldi's magic eraser sponge. the reason was to have Waxoyl in the joints of lettering, panels and lights. corrosion stopped. Downside; takes a day for the white spirit diluter to dry and leave the wax before buffing. The car is now encapsulated in Waxoyl including fabric top and leatherseats. ravages of time caused by oxidation stopped. No Oxygen, no corrosion. Gary
