I've personally used non-abrasive compound such as Buff Magic and it worked out great...not sure if I would try an abrasive based...but I am sure someone else has experience and will pip up quickly.
Did my the boat hull with finess it II. some spots needed more so i used the collinte cleaner wax then followed up with finess it II. i have clear coat over silver imron.,
Has anyone tried "Rejex" by Corrosion Block? Phenomenal shine, it makes the Formula Imron finish look like a mirror. It does not have chalk removing properties, but it is an excellent finishing product.
Here is the link for more information. http://www.corrosionx.com/rejexmain.html
