What you're talking about is the cavitat machine invented by Bob Jones. Yeah, I have come across this and I have found people that say it is the best thing to heal from cavitations.
But it may also be hard to find. Sometimes a sure-fire way to heal cavitations is just to open the hole up anyway and see what comes out! <img src="/ubbthreads/images/graemlins/crazy.gif" alt="" /> That
s how I had mine done and it turned out well, U can say.
And thanks for the link. It is very informative.
