which will give a stronger and cleaner joint.
GEL may thin over time but thinning does not affect
performance of flux, refrigerating flux slows thinning.

Flux Users Comments
“Again, thanks for the terrific service that your company provides. I wish all companies would be as helpful and efficient as yours, especially when dealing outside of North America.”
Ray B (S Australia)
Your flux saved my life!!
“I've almost gone through a whole bottle. Between the flux and the silver solder life has been a lot easier on me as I've soldered lots of turnouts, throw bars, and feeders along my 6 scale mile long, double tracked mainline.”
Ted Y (Model Railroader)
Supersafe™ is the Best
“I will not make any type of electrical connection on my Model train layout without using ‘Supersafe®” and H&N Silver Solder. This combination assures every connection is the best possible. I also find “Supersafe®” very useful at work.”
Tracy A. (NASA Tech & Model Railroader)
Great for Brass Rail
“I last purchased this product at a Hobby show in Long Beach, CA while a visitor. It is the very best for soldering wire to brass rail. I’m almost out and was happy to see the product review in Railroad Model Craftsman. “
Chester M. (Model Railroader)
Boy, is this stuff Good.
“For someone whose soldering skills aren’t that great, this product allows me now to make real good solder joints.”
