Which paint to use?

[patrickbwells]

I am restoring a 30 year old woven roven glass hulled sailboat. Most of the interior has been gutted and I would like to paint the inside of the hull (if possible) before I start glassing in bulkheads and cabinets. The years have not been kind to this boat and the hull is covered with several different type of paints and adhesives which I have been diligently trying to remove. I have sanded, scraped, chipped, and used various strippers but the rough texture of the roven woven has made complete removal impossible. Is there some type of paint, such as an epoxy or polyester primer, that I can paint the inside of the hull with without interfering with my ability to glass in components later on?

You need to get all of your glass work done before you paint. Try using a stripper to get at the tough stuff that sanding wont remove.

I use a grinder with a coarse disc to remove the paint and scuff the surface so the tabbing will have a good bond. Grind until all, or almost all, of the paint is gone where the new tabbing will be. I want to bond any new work directly to the original fiberglass of the hull. For areas where you will just be painting, I would leave well bonded paint in place, it is just too much work to remove. A light sandblasting would give the surface some tooth for the new paint to adhere.

Definitely need to get the paint out from under any intended glass work.
If it's warm enough there is a non toxic, non fuming stripper called Aqua Strip that works reasonably well without damaging the fibreglass.

After all is said and done, Interlux makes some good single part polyurethanes (the "Brightside" series) that seem to work well, including one specifically intended for inside lockers, lazarettes etc (it only comes in white or gray, though)

You'll be amazed at how well even the heavy roving pattern turns out after repainting - and no more glass-itching after crawling around in these spaces!

Here's the link for the interlux site. Poke around in there lots of good info. Good luck on your project.

You can't paint and then expect the new glass to stick to the interior of the hull reliably. I would grind the roving down a bit to get rid of the paint and then add a few layers of glass cloth, to give build up the interior of the hull again and to give you a smoother interior hull surface, to glass the bulkheads and furniture to.
