I'll never do this cuz I have waaaaaaay too many other weird projects.
It came out of a scheme of mine to measure the fluid level in oil wells
using microwaves.
I have done a lot of looking into blister repair and even have done
some of it. What I find is that blister repair is mostly a scam that
fails about 80% of the time. As others have pointed out, blisters are
really only a cosmetic problem. I have NEVER heard of osmotic blisters
causing hull failure on a boat made from woven fiberglass. I HAVE
heard of severe problems in hulls made from short strand mats. If
anybody has ever heard of a hull failure or accident resulting from
Osmotic Blisters, i'd like to hear about it.

Thanks
