All I can say is that 3 years ago I POR-15ed my deck, top-coated it with 
latex yellow from Home Depot and three years later it looks great. Two 
years ago I POR-15ed my snowblower chute and after two winters of 
blowing snow, dirt, and small rocks (things happen) there is not a ding 
or scratch in the paint. However all the latex paint was blown off the 
inside, exposing the POR-15.

Scrape off the old rust, sand, POR-15, do another coat. The only thing I 
have found that it does not adhere to like a rock is pure Al plate.
