Default Possible to go from bottom paint to just gelcoat?

As the title says, once a boat has been bottom painted, is it possible to convert it back to a clean hull? Or this is going to be "sand everything down to glass" kind of possible and therefore unreasonably expensive?

OK, fair point. I guess the the answer is "unreasonably expensive".

I've done two. A 23 Seacraft , and a 24 Grady. NEVER again. IT has to be something YOU want to do . Crazy labor intensive and hard. I will say when complete you could not tell either had ever been painted.

A skilled soda blaster can remove the bottom paint with minimal impact to the underlying gel coat....and then you will only have 2,694 hours of wet sanding/compounding/polishing ahead of you.


Painting the hull is ever so much simpler.

I did my hull. IF I had to do it over again, I would never buy a hull with paint! Was it worth it? Sort of. I gain some speed(4mph top end) and lost some rpm(400) at a 30mph cruise. I dont look like a smurf when I rub the boat while climbing out or into it after a dive or swim anymore. But the the cost was way to much for the return I think. I wont even consider a boat with paint now but that is my preference and how I use it(lift and trailer kept).

I did a couple of 21ft boats using a product called 'PeelAway'. It works as advertised and got all the bottom paint and most of the primer (barrier coat) off pretty easily. Then wet sanded with 320 where there was any primer left, followed by 800, then 1500, then wax. Came out like new, but is a lot of work. Easiest way is to drop the boat off the trailer and put on blocks or tilt to one side.if you can. Doesn't cost a fortune in product, but you chew up a lot of your time to get it right.

Why put yourself through all that work, the fish don’t care and you can’t see the paint from the helm.
Having a non-painted Hull is overrated.

It took one guy about 3 days to wet sand mine off with 220 and 600 grit using an orbital air sander on a 26' cat on jack stands. he spent another day with white rubbing compound and 2 coats of wax, and another day dicking around to remove and place the hull back on its trailer. You do not want to dry sand bottom paint.

I just did it. It really sucks. Use peel away then hit it with a pressure washer. Do that untill it doesn’t work anymore. Then you have to wet sand the rest off. Then re sand with higher grit. Finish it off with a compound buffing. It’s super labor intensive. I would have just kept it if it wasn’t already half way off from the previous owner.

Many moons ago I bought a bottom painted boat. I kept the boat on the trailer, so it didn't need it. I just left it alone and worried about more important things.

I had a bottom painted 25’ that we sanded all the paint off and regelled from the waterline down. Applied gel with a roller and paid a lot of attention to flow out especially on the sides. Not the same as sprayed, wet sand and buffed but very nice with a fraction of the work.

A friend of mine wanted to do the same thing. Used Easy-Off oven cleaner on a warm day. It worked well, and got down to the gelcoat, but it was pretty stained. That's when the orbital sander and the 220 and 400 grits came ou, then buffed with 3M Fiberglass Restorer.

It wasn't as bad as some say, with a couple of guys working together, but not my idea of a good time.
