you soda blast the whole hull or just where the bottom paint was?

Tony only soda blasted the bottom paint and the good news was no gel coat blisters were found.

Strike that last "forward looking" statement. Upon further review it appears the hull below the waterline has a bunch of blisters. When I cracked a couple open it seems to be just an air pocket with no osmosis type liquid inside. So I guess I get the dremel out and open these up, then quik fair and sand it out before several coats of barrier paint.

I would make the mat about an inch wider all the way around becuase it does stretch. I was always told to put a layer of mat down before a stichmat or 1708. I will tell you what soda blasting the bottom of a boat is the best money ever spent, I will never sand a bottom again after I got the bottom of my boat soda blasted. Keep up the good work.
