Default Bottom paint removal

I am thinking about buying a 94 2000SC but has some really bad bottom paint, pealing and chiping looks like 2 maybe 3 layers. (who puts bottom paint on a boat this size...gezzzzz) anyway want to remove it and back to a glossy gelcoat!

Todd

Todd...
at west marine they sell a bottom paint removal gel that really works well....get the boat up on stands and lay a tarp down....tape the top of the hull to protect the gel coat you don't want to paint....use the blue type tape........works the best...
then open the gel up and spred all over the black hull paint......let stand for about an hr and scrape off.....then wash off.....use fine sandpaper to rough up the gel coat...check for bubbles and repair with bondo....or gel coat repair kit....
then use a primer and the black bottom coat....we use this stuff for a hull that sits in salt water........

works great and looks cool...

Sounds easy, but I didn't want to repaint! could I just buff it out after paint removal?

probably can..but you need to get it right down to the gelcoat and then wetsand and polish...why not go back with bottom paint??


SP

boy howdy!!...I went back and looked at your photo's...wetsand and get it down the gelcoat...then compound it and polish..that's gonna be a lot of work....might concider taking to someone that specializes in boat gelcoating...they can make it look like new!!...

Todd......There is a hand tool that takes the gel-coat off of boats........usually done because of bistering on the hull and make sure your project boat doesn't have this problem........This remover takes everything off and you would start with a clean surface. Then a new layer of gelcoat gets put on. Yeah alot of work and it problably is not cheap to get it done by someone else but another idea. Talk to your local fiberglass guy about this. I have seen it done and the hand tool looks like a giant hair shearer, if that makes any sense.

Or again alot a elbow hours with the sander to take this layer off. With that said you will most likely get into the gelcoat trying to sand this bottom paint off so you will have to give the hull a coat of something........

Personally I hate every spring when I have to sand the bottom of my 3000 and put some touch-up bottom paint on. You have to have the white suit on, goggles, mask, rubber gloves and I swear you are pooping it out a couple days later.

Whatever you decide have fun!

I got a price of $650 to have my 2300 soda blasted. You would still have to repaint or gelcoat. Don't think you would be able to polish it back to original once it has been prepped for bottom paint.

That sounds like a miserable job nearly beyond my comprehension, Todd, I think you're nuts. LOL

If it were me I'd remove all the loose bits then just bottom coat it again. After all, ya can't really see much of it when it's sitting in the water!

How about acetone? It works pretty good as a general paint remover and it does love to clean fiberglass. Just not familar with bottom paint so maybe it is not strong enough?

I was thinking I could use the bottom paint removal gel followed by acetone and buff it out. I really don't want to put the bottom paint back on but...unless i have to. (haven't bought the boat yet but need to know what I am getting into if I do)

Todd, not sure if you need bottom paint in salt water, but we couldn't live without it here in the Midwest. My advice to you is to have a professional repaint the bottom (they will take off the existing paint and do it right) and then every year you can use bottom paint and just touch it up yourself. A few hundred bucks up front, then $100 can of bottom paint lasts us 3 years so far on repainting the entire bottom of our 2800, so it goes a long ways if you have a good foundation. So much easier than having to acid wash it, and keeps the grimey beard off of it here. Sounds like it's too much work what you want to do, but good luck either way!

It is going to be very, very, very difficult to get the bottom back to Pre-bottom painting. The process to apply bottom paint typically calls for sanding the gelcoat with 80 grit sandpaper. The process of removal is going to be even worse. sand or soda blasting will definitely bang up the bottom. Your best bet would be to remove the bottom paint, prepare the hull then barrier coat and repaint. Otherwise, you're going to need to re-gel coat the bottom. Even that will not look perfect.

Its not the color, its the condition of the paint. its really nasty. I am going to strip it and repaint. Sounds easy ....but it's a messy job and will take longer in the cold. most likely a few weeks and several cases of Bud Lite...lol

Welllllllll I bought the boat, got him down to a GREAT price, its really in good shape, "Just a little" work to do, but that will keep me outa the bars this winter.... (mostly..LOL) Engine change and the bottom paint are the 2 biggest projects. Think I'll take the easy way out for the engine and just buy a Long Block and swap all the other stuff over. The paint removal is going to be a painfull process but I have all winter. I'll be posting pictures when I get this going in Nov.

Oct is busy for me as I have to work in the US Open 9 Ball Championships in Chesakeake Va, If anyone is in town from 16-22 Oct stop by the Chesapeake Conference center and say Hi.

I overlooked this. In saltwater you need antifouling paint even moreso than freshwater.

yo todd...

congrats with buying the boat.......sand the bottom untill it looks as smoothly as the skin of a baby........maybe you need to put on a new primer and then re- antifouling her with at last 3 layers of antifouling......that will do for the first 2 years.........and that you bought her much more cheap is only good in these times off financial crisis......have fun with her during the last days of the summer......and for the winter........ you have a nice project....

greatz, ed
