NEVER-DULL wuz created for the Navy fur shinin' the "TOP BRASS'S" buttons & HERO badges.--LOL Stinks like s**t when OLD, but still works good.
Had a WHITE Plymouth with little rough "bumpies" under the deck lid paint, from rust. Hit them with 3,000 grit sandpaper, went over them with Old type chrome polish, kept it waxed & it looked good for 3 years, until I could afford a COMPLETE paint job.
Iffin' you have paint cracks in your BLACK fenders, scrub them with a toothbrush & paint thinner, then rub the cracks with BLACK Shoe Wax & they almost distappear!
