I have just tried Armor All Extreme Tire Shine Gel (orange plastic bottle with foam applicator) based on a recommendation from VXCrazy. It has held up for several weeks now, keeping the clading a nice black color with no streaks. It looks a little streaky when first applied. But after a few hours, the streaks go away leaving the clading with a nice "wet black" look. The wet look remained for several days. Got a lot of good comments on the appearance.

I have not tried the Meguiars Endurance yet. I did get a bottle from WalMart the last time I was there since the local auto parts store did not have that specific Meguiars product. The plastic bottle is a grape color and is called Endurance High Gloss Long Lasting Tire Protectant Gel. I assume that this is what others are recommending.
