por15 paint on steel keel

[Syntonos]

Has anyone had experience with por15 rust paint on their steel keel? The process looks sound for boat applications, I'm just concerned about bottom paint adhesion.

I used that on a Catalina 22 swing keel, cast I believe. I sold the boat a year later so can't tell if it held up but I figured it should.

You can paint over POR-15 so I should think it is fine, but worst case you could paint it and then bottom paint it. I am certain I have heard of others doing this.

Here is a nice article.

I applied POR-15 to the cast iron keel of my H28.5 when I bought the boat about 8 years ago. While I should have stripped the keel to bare metal, and applied the recommended metal/etching solutions prior to painting on the POR-15, I didn't have the tools or time to do so properly. Instead, I spot sanded and applied the POR-15. I believe that I roughed up the cured POR-15 to give the bottom paint, applied a few days later, some "tooth". It has held up well.
