I have an F-150 with GREAT BIG outside door sills around the windows. It's a 2004 so they were starting to get a bit old looking. We carry Griot's Garage Rubber Cleaner, so I decided to give it a shot. Unlike rubber treatments like Armor All that shine rubber up, this product is designed to actually CLEAN the rubber and recondition it prior to treatment. I frankly wasn't expecting much because I have never had any luck in the past with products that made this claim. I was very impressed with how well it did. It took a bit more rubbing than expected, bit it really did pull the old, grimy, rubber out and made the seals look much better. Take a look!

Overall a good product.
