I was thinking of that, it comes in white and I've used it before and it levels to a nice smooth finish. Can you use it without a covering coat?

Use interprotect 2000e barrier coat... the fact that it is underwater won't bother it.

What paint below the waterline on a hard dinghy?
The gelcoat on my dinghy was toast, and the PO's repaint was fading and scratched, so I painted my dinghy last year with Interlux Brightside Polyurethane. This paint is for topsides only. I thought I would be putting the boat on deck occasionally, but I ended up not doing that. It turns out that three weeks in the water does not make this paint happy, it bubbled up quite a bit.
But the kicker was that over the winter with a plastic tarp over the upside down dinghy, water got through some pinholes in the tarp and was held against the paint, causing an rash of little bubbles/blisters all over bottom of the boat.
The topsides are still OK, I might be able to get away just from the waterline down with a hard antifouling/bottom paint... but I want an white or offwhite.
I'd spray gelcoat, but this is a lapstrake style dinghy and the wet sanding would take me forever.
What paint do people use below the waterline when sections of the gelcoat have been ground down and removed?
