    Default What's the best way to strip old paint of an aluminum boat?

    I just picked up a 1959 Lone Star Malibu. The boat is in pretty good shape (minus the seats) but the paint job is pretty bad. It looks like it was painted with no primer and latex paint and it's all flaking off. I have a few ideas on what to try but was looking for any input as to what others have done? thanks.

    Does anyone do Soda Blasting up where you are? The Lone Star is a classic and would look great re-finished. When I was younger my Dad have a Black Lone Star Mustang from the factory........ or you can sand it.

    Yup, blasting or sanding are options...so is plain old nasty spray-on oven cleaner. Work outside on a calm day and wear gloves and protective eyewear...spray on, wait 10 minutes, hose it off. It will take it down to bare metal then you can sand, prime and repaint. Costs about $4 a can though. Also works good as a cleaner/degreaser/stripper for prepping outboards for paint...aluminum ones, that is. Never tried it on f-glass...might eat it up.

    Soda blasting? what the heck is that? is that like sand blasting? I'm not set up for sand blasting. Don't have the equipment and my compressor is too small I believe.

    Anyone ever heard of Talstrip 2? (photo attached) Another aluminum boat guy told me it will vaporize anything on aluminum. They use it to strip airplanes. Have not tried it yet though.

    That stuff will work. You can also use regular paint store paint stripper...the thick kind you brush on, then scrape off. That's what I did on my tinny, and it took off three coats of paint. If that's really latex-based paint, it'll strip right off, slick as can be.

    There will be some touch-up stripping to do, but the same stuff works on that, too.

    If you use that, follow the directions on the can carefully. Apply it thickly, brushing it on in just one direction, for best results. Don't put it in plastic containers, or it'll melt right through 'em. Use metal cans. Use a natural bristle brush, since some of the synthetic ones will melt in the stuff.

    Just do it outdoors, since paint remover is nasty stuff to breathe. Wear really, really old clothes and shoes you can throw out when you finish. Also, good rubber gloves. Wash off any you get on your skin right away. It'll give you a burn.

    BTW, I love the lines of that boat!

    Sure...go ahead and laugh at my old aluminum boat. It's paid for!

    he knows what he's saying. WEAR GLOVES. take your time brushing it on or you will get it all over your self. you wont feel the spots falling on your skin till about 40 sec later, just drop what your doing and get it off if anything keep a wet rag next to you.

    If I see the picture correctly that paint is loose and most of it will come off with a pressure washer. Use a 3000psi and at least 4 gpm power washer with 0 tip. If you don't think it will work, buy a random orbit sander palm handle by porter cable with vacuum attachment (or without) works really well and it is a must have for any sanding job, velcro type sandpaper from 320 grt. to 40grt. course available. Give yourself a break and stay away from nasty paint removers.

    Hello all

    I am finishing up on the sides for my boat.
    I used brand name "STRIPPER" and "STRIPEEZE" thick paste let it set for the recommended time and used a heavy duty paint scraper to remove old paint.

    I also used my sander to complete the job but that mostly polished up the aluminum.

    I WASHED the boat then used mineral spirits to ensure ALL the paint srtiper material was off.

    I had a choice of primers to use.
    ZINC CHROMATE or SEM (mfg in North Carolina) brand bought locally at an auto paint store.

    Hand spray.

    Both have "SELF ETCHING" properties to adhere to the aluminum.

    http://www.nefla.com/boat/

    As you can see, I have NOT applied the finish coat.

    I removed the hardware (cleats etc) to allow me to finish the deck area.
    My 1600 psi pressure washer has removed ALMOST all of the paint top side.

    YES, I will use my THICK PASTE to remove the remaining paint.
    sand the metal, apply more primer.

    I plan to get a QUOTE from the local truck bed spray company to apply that material to the deck areas. NON SKID

    If that proves to costly, I may buy it in quart cans or use non skid paint.
    In the Navy, we used to simply ADD SAND to the paint. (I retired in 1990)

    Thanks,
    Bill

    I'm going to try this stuff when it arrives in a couple of days. Apparently you can just pressure wash the boat and all the paint just falls off including the areas around the rivets.

    It's also ph neutral and is environmentally friendly. http://www.m-tc.com/efs2500_home.htm

    I'm wanting to get mine to polished aluminum shine. Surely, I need to seal it. Any mistakes I can avoid?
