we used the POR15 to coat a windlass gear case and motor that was thoroughly rusted from 15 years in a damp chain locker - we sandblasted the csae to bare metal first. I don''t know how long it will hold up but it''s a durable finish. We also found POR15 coating on our stainless water tanks. These were five years old and failed due to corrosion at the welds. On investigating, the manufacturer believes that the POR15 coating contributed to the corrosion as it limited the oxygen that could reach the stainless - oxygen is critical for stainless to inhibit corrosion.
So it may be good for some applications and not others...
