Great results from a noob.

I’ve been soldering, brazing and welding most my life but never silver soldering. After asking around the consensus was this was the best and using the suggestions of how to prep etc I went for it. I needed to silver solder the end of the stainless steel counter top together. It worked great and came out perfect. Little buffing and you couldn’t tell it had been soldered. Scored big points with my wife as she got the stainless countertops she’d been wanting.
