To use up a little I had left over I brushed a few welded joints on a chain link fence that had started to rust to see what the sun would do to POR-15. Did not take long for it to deteriorate (a couple of months). Six months later it is dull black and broken down completely. Touch it and you get a smudge on your fingers much like what you get when sanding paint or picking up a piece of chalk. I can rub it off down to the bare metal once more. If whatever you coat with POR-15 will be exposed to sunlight the manufacturer does indeed recommend painting over it.
