product does not melt or flow well.

I tried to bond two metal pieces together. i used flux and a propane torch. product just doesn't melt easy or want to flow. I even tried to practice with it and had no luck.

Not for stainless

I tried to use this to install a front sight onto a stainless steel Ruger Blackhawk. I've been soldering, brazing, and welding since I was a teenager (a very long time ago). If your working on stainless, this is NOT for you.

Can anyone get this to work?

I've used Force 44 for many years. And I also use higher temp silver solders. But for the life of me, I can't get this stuff to adhere to anything, especially stainlesses. And the Copper Bond Flux is being used. Originally it was purchased to reattach a shotgun rib. This is a tedious process (for me) anyway. I thought the complications of that job were the problem. But since, I've tried a dozen times to attach sight ramps and such with it, and always remove all and start over with a solder that works for me. If anyone gets it to work, I'm missing something not in the instructions.
