Greetings,
When using POR15, place a couple layers of cling wrap or saran wrap over the top before you snug down the lid. You'll never have a problem re-opening the can.
Mr. NW. Yes, POR15 suggests you leave a light layer of rust on the surface to aid in bonding. I've never had a problem either leaving the skim of rust or applying to clean metal. The trick is to get a continuous coat so no moisture can wick through any voids in the paint layer and reach the substrate.
Rustoleum is very popular due to low price and aggressive marketing. It is not a bad coating but is not comparable to POR15 in toughness.
I was at a friends place years ago and he had used a piece of 1/2" re-bar to stir his can of POR. He gave me the re-bar and his 5lb sledge and dared me to chip the finish. No go. Half a dozen good whacks on his anvil with the sledge made no mark or impression.
No affiliation with the POR company, just a satisfied customer...
