I have some ambroid but I prefer Tanax 7r, Snake. Yes I was at Rob's, Brian, and bought a bottle of the Squadron stuff to try out. Thanks Mike. I'll get by. What bother me is that a hobby shop can't get something from his suppliers but ti seems to be available all over online. You may recall that Tenax 7r had issues a couple of years ago. I don't know, maybe their plan is to run supplies low to justify a price increase.
