Long Term POR-15 users - Are yo still happy with the product?

would that stuff work on steel rims?>
would the silver pass for argent from 50 feet away?
Does it go on like paint or seam sealer?

I acid dipped 4 Rallys and 2 made it past their prime and paint session. The other 2 gave me the finger and rusted like they were stored in salt water. Im ready to paint them black, then silver with POR-15 like the truck bed on their website.
