Consider dry ice blasting. That's what was recommended to me. It leaves almost nothing to clean up and is very mildly abrasive. Some of the media can leave pocks which need filled and fared. Ratchets the price up considerably.
I don't think my 1989 37+ is barrier coated. But when i had my rudder rebuilt 3 winters ago the fiberglass guy finished it with barrier coat. At haul out this past spring guess which one had pimples, the hull or the rudder. That's right, the rudder. So 2 seasons in the water or 26 years in the water? I say if the gelcoat and original fiberglass lasted this long leave it alone.
