Review on TIRE RUBBER VINYL PROTECTANT 16Oz by Derick Johns

Excellent product. It's similar to Mother's Back to Black in its intended use, but TRV is silicone-free and less prone to staining from water and other car care products. The door and window seals on my 1999 Porsche are original and what they look like. They turned gray and hard. Not only did TRV make them black again, but they made them nice and soft too. This product also claims to have UV protection, which is important to me as I deal with the intense Texas sun.
