I have a 10 year old Volvo wagon which I like to maintain. The vinyl trim is badly oxidized and dull from the sun. Does anyone have suggestions on a product that will return the trim to it's black color. I tried one from Pep Boys that worked, but it got dull pretty quickly again.
I've always used Armor-All and it works great but you do have to use it at least once a month to keep up the shine or after each time you wash your car. That's the absolute best product you can use :-)
