I use to detail cars to make extra money and I found that 303 Aerospace Protectant is a great protectant to use on cars and boat seats, and it does not make them slick like some of the other products. I have about slid out of my seat when I use to use the other products. Armour All has been found to harm the materials that it is supposed to be protecting. I just use the Armour All I have left on my Trolling motor shaft so it slides loose easier. You might try Oxyclean on your seats, it sure has worked for me on a lot of different stuff. I don't know the effect it has on the seats, you would have to read the label. Good luck, Wes
