Well I guess I'm a glutton for punishment when it comes to car care products. I like to try everything, then make a decision based upon their preformance. Right now as far as the cladding care goes. #1 GM Cladding Cleaner Kit. PN 89020818. About $20 from the dealer. The dealer needs to buy a case of 5 or 6 in order to get this product delivered to him, but if the dealer is right with you, he will sell you one. I'm sure after the dealer sees how great this product works, he will start using it to recon used car flares, black trim, cladding, ect. #2- 303. I have used this product for years, and sell it in my store. Great looks, durability pretty good. k#3. All the tire coatings look good too, however they are a bit greasy, and eventually wear off also. Probably the worst-Armor all and Armordillo. Tried them all on my 02, and GM's is still the best, especially in the snow, rain, and mud of Pa.
