I had my Herald chassis blasted and then used POR15.
I did use the Marine Clean & Metal Ready first as I had read reports of the POR15 peeling-off when put onto bare metal.
POR15 is a little tricky in that it claims there to be a narrow window of time between coats unless you opt to prime again. I did actually tend to use the POR15 self-etch primer as I left the chassis some days between coats.
The POR15 itself gave a very imrpressive finish - hard and shiny (gloss black). I then used the silver topcoat and feel that it has a much softer (ie easily scraped) finish.
Just my thoughts.
