I altready got a quote on the epoxy sealer trick, $6100.
Plus I've heard many horror stories about how they sometimeas can't control the flow well enough and they get puddles in the low points which effectively make a 1/2" pipe flow like a 1/4" pipe.
Either that or sometimes they do not get 100% coverage.

if it was cleaper than repiping the entire house I might have gone for it, but seeing how it is more expensive for less work and more risk, I said no thank you.
