Re: quick bottom job!??!!-- !!
I had the shipyard do the same blister removal process for me 3 years ago. They used 2 coats of barrier paint over the reepoxied bottom. Then 2 coats of bottom paint over that. No blisters since then.
It would be foolish to skip the barrier coats after all that hard work. It goes on quick and easy compared to grinding out blisters.
