commodore coatings
 

Does anyone have experience with this product line. My dealer sold me on a interior fabric treatment from this co. that protects the interior surfaces from stains for 5 years but it seems to be a waste of time. They still stain at the blink of an eye you can't get it off. The dealer is attempting to clean them today for a 2nd time as they made a total mess of them yesterday.
I was just wondering if anyone else had purchased this treatment from a dealer for any vehicle and what kind of results you had from it?
