Here is the thing. What do you do if you do not have access to a sand blaster or someone who does sandblasting? I don't and its a big pain if you are a backyard/driveway builder like me. So not that many choices. With the POR, you are supposed to sand, wire wheel all the loose stuff, degrease, then spray it all down with their etching product, rinse, dry and then apply.
One thing I have noted over the years is that the black they now sell is not the same black they use to sell. Just not as good. Frankly, I always found the silver to be the better product anyway, with the black as the second coat. So I am always silver as the first coat.
