My boat don't have dock bumpers so there's really no stopping place to change paints anyways. So, from what I'm reading, it's better to use a non-epoxy paint on the bottom? Can you explain why this is? I would have thought that epoxy was the next best thing to gel coat but I don't know, I'm asking. You guys have more experience than I do with this so I'm willing to listen, just explain.
I guess you would have the boat in the water and mark the waterline. Remove the boat from the water. When painting the bottom bring the color an inch or two or three above the waterline mark. A bootstripe if you want.
On the epoxy bottom paint, there is what is called an epoxy barrier coat that is applied over the bare fiberglass(polyester resin) to help prevent osmosis through the fiberglass hull. Many times this barrier coat is used after blisters in the fiberglass boat bottom have been repaired and also for added protection. Then the barrier coat is overcoated with bottom paint.
But yours, S10, will stay mostly on the trailer so an epoxy barrier coat is not necessary.
Hope this helps.
