  • Repairing flaky, chipped bottom paint

    The bottom paint on my 171S looks... like it needs attention. There are big chunks that are missing, down to the gel coat it looks like. I have the paint to do this, but how do I fill in the depressed area where the chunks are missing?

    Is trying to restore the gel coat at all a task I should undertake instead?

    If I could figure out how to add a picture here I would show you what I mean. https://photos.google.com/search/_tr...btC9dtbH3d_tpD

    If you do not want to have an impression then you would have to strip all the BP off and paint it once again. Just my 2 cents.

      As stated the best approach would be to strip all the old multi-coats of bottom paint. There are a number of threads on how to. Some guys have used EZ off oven cleaner.while others have had it soda blasted off and start fresh.

        If i go through the trouble of taking it off, is it worth restoring the gel coat? Or repainting fresh?

          do you ever leave your boat in the water? You can also just re-paint and use the boat as is, but stripping and repainting is the only way to get it uniform.

            Spray on oven cleaner wait two hours. Pressure was. Repeat till hull is free of bottom paint. Sand bottom to 100 grit(cover mouth) lightly. Youre not trying to remove material just give it tooth. Brush on a coat of epoxy- entire bottom. Wash with dawn and pressure wash. Roll on two coats of ceramkote99 and your hull will never have water intrusion and it will not chip off. I sand between the epoxy and ceramkote but some dont.

            Or just ceramkote over it all and go fish!

            Best of luck

              Re-gel coating is a lot of work if you do it right. Otherwise its not worth it. If you do regelcoat, its worth flipping the hull to remove paint, fair and apply the gel coat. Gelcoting a boat bottom on stands or trailer would be miserable.
