You may want to consider optimum compound and polish rather than SSR. I started with SSR 2.5 and 1, but moved on to optimum. SSR dusts a lot leving much to clean up. Optimum also offers twice as much product for the same price.
303 protectant is the only product that I have tried so far that has turned my brown rubber trim black again.
Tuff stuff is a good and cheap product for carpets and upholestry.
I still have a lot of waxes to try, but I did like
NXT a lot. Good luck on the hours of work ahead!
