NEM, interesting question.....after chemically stripping, sand and soda blasting, I personally would not go naked on the hull. The boats I have done were all 20 years old, so they had some mileage on them. When you blast off, or for that matter, even chemically peel off or sand the bottom, you'll find dings and scratches that you never thought you had that were covered up by layers of bottom paint that you will want to fix, probably with epoxy...so that will require a finish. And you also open the pores of the gelcoat, especially after its seen 20 years of use.....the blasted finish will look and feel like sharkskin....even if you peeled and sanded, you will have that "texture" when you run your hand over it. And most of these older boats use regular polyester resin, not vinyl ester, so I'd sleep better with "something" on the bottom.....I think after you scrape or blast your 233, you will see its not pristine anymore and needs help just to look good. I mean, you can do multiple step sanding to get a smooth finish, but that is a TON of work.
I have heard, but never used, that Interlux makes this VC Performance Epoxy finish specifically for hull bottoms that are trailered or rack stored...its not an anti-fouling......maybe this will work for you...seal the hull and give a nice hard finish that looks good...it comes in white.
