Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <rblaisdell-at-juno-dot-com> Thanks for all the help on how to cure NST's. When depotting a NST, I would assume(I don't like to assume) that one melts as much tar out and then uses some sort of volatile solvent to get the rest off. What solvents have been found to be good for this? Peace, -------Ry--------
