Bottom Paint Source

[Belmont Resident]

Being a painter, if you use a good quality paint and clean any loose or chipping paint off, then seal it with a fresh coat of paint you have effectively sealed in anything that is under the new paint.
The key to a good long lasting paint job on anything you are going to paint is the prep.
You might look at Sports and Marine Parafunalia they might have what you’re looking for.

Good luck
