Hull blisters

If you wish to repair some minor blistering, and it later fails, it will cause no more harm to the remainder of the hull but anytime a boat is left in the water, especially in brackish or salt water, osmotic blistering may occur unless the bottom has a barrier coating on it. Of course if you barrier coat you would want to bottom paint it too. The solution is to leave it out of the water as much as possible. I've experimented with my river, also brackish, leaving boats in for varied amounts of time and even pulling and cleaning after one or two weeks won't prevent blistering. It seems the accumulated time in the water without completely drying is what counts, in my experience. Others may have other opinions. I hope this helps.

79, I never heard the part about wax.....usually deal with painted bottoms with blisters in our location....what does the wax do to help the blistering??
