Barrier Coat

[Futsal Fred]

Last Fall I did a ton of scraping and stripping and sanding and got most of the ten layers of anti fouling paint off the hull of my Hunter 260.

As soon as it stops hailing, I'm going to finish the job, but am confused about what next.

I talked to Hunter and they recommended a "barrier coat" since it'll be mostly trailered and only see fresh water.

Can some kind soul point me to a product? I really don't see the need for a coat of paint but since I've had to do some light sanding to get the last of the primer coat off I figure maybe a couple coats of wax isn't quite enough.

Any thoughts?

Once you have sanded into the gelcoat you have broken the barrier and you should use a barrier coat. Then you can just paint it with a hard paint. I do not think it is acceptable to expose the barrier coat to the sunlight.

You may want to check with the paint mfg for their opinion on their product.

If you were under warranty your warranty would be void if you sand the bottom without a barrier coat.

I think the standard at this point is to use an expoxy based barrier coating then paint with your choice of hard or ablative paint.

Here is the info sheet for a barrier-coat: http://www.yachtpaint.com/MPYACMDatasheets/Interprotect_2000E+eng-usa+A4+Y+20100614.pdf . I don't see anything that says that you need to cover it. Still I would call and ask( 1-908-686-1300 ). Even if you are dry sailing though I think you should add a coat or two of VC17 like pepto suggested. It is fast and wears so that sanding it off is never an issue. If you painted with a modified-epoxy you would also get a hard and fast bottom. And if you never worried about anti-fouling you could just sail on it for many seasons.
