I wanted to publically thank JT Mega-Steam. I response to a post I made on a recent thread that I run with smoke units off because my wife doesn't like the smell, they sent a sample of their "NADA" (No Scent) smoke fluid. It works as advertised. There is the barest trace of a smell but not enough that my wife objects and it produces a lot of smoke: frankly, I think the fact that I have obtained a "smell-less" fluid alone means she is happy with it. JT also sent some eliminator fluid that would help burn off old scent but most of my locos were pretty dry since I had never filled them nor run the smoke since testing each when new.
It is fun to run with smoke. I will sometimes run without it still: I often set my locos to running for hours on end "unattended" while I work on the layout, and I will continue to shut off the smoke then because I don't want them to go and run dry, but it is fun, as tonight, to run three big locos with gobs of smoke. Really filled up the celing with a nice cloud of smoke, and the puffing really adds to the fun of run the locos. I definately appreciate this NADA fluid. Great stuff.
