Ooltewah - Nice! We are neighbors.
If I can ever be of assistance, just shoot me a PM or something.
The 303 is great. Be sure and follow the directions though as far as how to apply. As for cleaning, I have never had to "deep clean" vinyl, so I have only used soapy water washes or interior cleaners (DP Total Interior Cleaner is my favorite for interior vinyl).
