Re: Hull repaint Jeanneau 54DS
Had my topside painted about 4 years ago. Sprayed on, indoors. Final bill was in low 20s US, iirc.
However, it wasn't straightforward. I had to have the old acrylic paint fully removed first. It would have been less, if it just needed a rough sanding over the same base.
It was the first repaint since new and I could also see the interior ribs beginning to "print" through the topside. I'm told, when the boat is brand new, the heat absorbed by the dark paint can cause the exterior fiberglass to cure faster, or something like that, and you can see the faintest ripple where a rib was behind the hull. You couldn't feel them with your hand, these were subtle. Dark hulls show every imperfection and, while it took light at just the right angle to see it at all, it drove me nuts. I had that all faired out before repainting.
I used Alexseal, which is made by the original inventor of Awlgrip. In the same original factory! Reportedly, his non-compete ran out after selling, so he got back in the game. Awlgrip is no longer his original formula anyway, as some of its components were banned. He felt he could make a better formula than just substituting banned components, as well as make an LP paint that was more repairable. After four years, I've been happy with it, but have a small nick here and there. I'm going to test the repair theory this winter.
