My cockpit has a few small areas that have worn thru to the primer. My thought is to get a shaker can of flat white paint and fog those areas. I then usually wax it with a coat of 3m wax. Any suggestions as to what type of paint to use-laquer, enamel?

Any suggestions would be appreciated.
Thanks

Your post is confusing, because the C25 is covered with gelcoat, and there's no primer under it. That suggests the possibility that your boat might have already been painted. Nevertheless, I don't see any reason why you shouldn't touch up small bad spots in the manner you suggest. I never tried it, and the only risk is that the paint might not wear very well, but if you need to remove it, small areas should be easy enough to remove by using a paint stripper <u>that is specifically designed for use on fiberglass gelcoat</u>. (Don't use the stripper from Lowes or Home Depot, because they will damage the surface.) If it has already been painted, the stripper will not only remove what you applied, but it will also remove whatever paint someone else applied. I'd try it on a small area and see how it works.

If the area is already painted, then you need to be very careful to select repair paint that is compatible with it. Some paints won't adhere over top of the wrong substrate. And some, like lacquer, are likely to eat into the the paint below, leaving severe mottle and orange peel.

For repairs over fiberglass, I really like oil based alkyd enamel paint. Since both alkyd and fiberglass are polyester based, the thermal expansion is almost identical, leading to great adhesion over wide temperature extremes. It's very hard to find alkyd these days due to VOC restrictions. In recent years I've only been able to find exterior gloss house paint, but it works great. I've never painted my C250, but I've used alkyd enamel for repairs on the inside of the hull on my Trophy boat, and it's held up extremely well. In my case I brushed it on, but you may be able to thin it down enough to spray with an air gun.

But all this depends strongly on what kind of paint (if any) you already have on the boat.
