Removing paint

Does anyone know if, after removing paint from the topsides, you can leave the areas unpainted to restore the original color? This assumes the painted areas underneath are in good condition, other than being painted.

If you are asking if you can strip the paint off and restore the original gel-coat the answer is no. Once painted you would have to repaint or reapply the gel-coat.

Sorry to sound so ignorant, but I know nothing about the topic. Is reapplying the gelcoat hard, or is it much like applying a coat of varnish?

Gelcoat can only be sprayed if you intend it to look good. If you aren't doing the entire boat, the most difficult issue is getting to color to match as it dries different than paint in terms of color change.

Jotun,

Once a hull has been painted, it usually stays painted, as the rationale for the original decision to paint never goes away. You shouldn't assume the areas underneath are in good condition, or the boat wouldn't be painted...

A careful handyman can do a "looks Ok" paint job, not to be confused with the results seen from professional Awlgrip. I think its pretty unusual to replace gelcoat, you'd have to remove all the old, then professionally spray new. Cheaper to professionally Awlgrip.

Try to provide some additional information. Do you know why the boat was painted, and how? Why do you want to remove the paint? When you say "restore the original color" - is the boat any color other than white - if it is not white, you will paint again, as colored gelcoat at best doesn't last long, and once faded can only be brought back temporarily (say, long enough to sell a boat...)

I saw this boat for sale and the owner had started a topside paint job in a color I don't prefer, so I wondered how to remedy the situation. Because the paint is incomplete, it would need something done. I was wondering what the best solution would be. I guess you could always repaint with white. But then you would be trying to cover a color, which I'm guessing would require more coats and more work, much like house paint.

I would be uncomfortable trusting the paint that is on there now anyway, so you would have to strip it off before repainting anyway. Assume the worst, include the cost of a professional job. You didn't say how big the boat was, but I think a 40 footer would run in the neighborhood of 15-18k.

BTW, one thing that hasn't been mentioned here that probably should be. If any significant repairs were done using epoxy, to re-build or repair the deck or topsides, then paint is the only alternative. Epoxy is highly susceptible to UV damage and must be protected, however, gelcoat won't stick to epoxy...so paint is your only real choice.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

For ultimate satisfaction, it sounds like you'd better be resigned to removing the old paint, properly prepping the hull and respraying with a good 2part Polyurethane or epoxy primers and paint. Such a job, done properly will out-last, out-look, and out-perform an after-the-fact gel coat job.

What you are describing sounds like a bit of a botched DIY job, so putting anything on top is risky. Get down to the bare glass, consult your supplier of choice and use all the proper materials, primers, reducers, as recommended.

Doing anything else will risk losing the considerable investment of time and money on the project.

To be considering purchasing a boat in that condition should mean a substantial price reduction over the average for that model of boat.

Be sure you're prepared to take on a project like that. These days it usually means finding an enclosed place to work, few yards will let you sand and spray anymore. The costs of rentals, storage, lift and transport fees should be factored into your equation as well.

word of caution on spraying 2 part epoxy paints....... everything i read says NOT to spray them by the average diy-er. way too specialized equipment for that kind of spraying.

a few good books on refinishing bottoms and tops are out there with convincing pics of brush and roller jobs. but 2 part is what they recommend.
this is in my plan for a 20', but i also have smaller boats to practice on first. so i don't have ,as yet, solid advice to offer

someone smarter, more experienced, and better than i may give a differing opinion on what i believe. good luck to you.
