Just about to sandblast the bottom of my boat and paint it with POR15. I was wondering if anyone has any stories about POR15 that I should be aware. The supplier says it's good and I have spoken to a guy who works in a slip yard and he said he wouldn't use anything else. I was wondering if any customers who have used this paint system are of the same opinion.

I've used POR15+ for a couple of applications.

1) on my Harley's alloy wheels I used their clear coat over paint. It's been there for almost 5 years now, with little sign of deterioration and has been jet blasted more than once.

2) on my Fiat X1/9 rust. If done correctly, the rust will not return. It's all to do with the way the paint cures.

3) on my Harley frame. Not that it's prone to rust, but it is a very, very hard coating and is very hard to chip or sand once on.

Not sure if this is kosher but here is their website. http://www.ppc.au.com/

So, if it's on a steel boat, I'd say it would be very suitable, but it must have a top coat of some other type as it's (or wasn't when I used it) UV protected.
