501 is the Marine / RV polish and the 521 is the Marine / RV detail spray.
Just wondering how they worked out for you. I put 501 on my clearcoated factory wheels and could not believe the look , super shiny , bright and extremely slick . I drove out in the snow and salt and water yesterday and when I got home I could not believe the wheels where barely even showing anything . Extremely impressive !!
I wondered if anyone uses this combo on their paint and what your thoughts are .
