Plastic Bumpers

[HummerJim]

I would agree 100% that for black vinyl and rubber there is no better product than Black Again. I've used it on several of my cars for years and use it on the Hummer. I get it at O'Rileys and the newer cans say Professional Detailers Formula on the top of the can. If you've ever been to a Barret Jackson auction, you'll find one of the last things they rub on the tires and any vinyl before they put it up on the stage is Black Again.
