Rectorseal 14020 8-Ounce Nokorode Regular Paste Flux Tool

Tried this for the first time today, I have been doing stained glass for a quite a few years, always used a water based flux, but not anymore after using this, you use less the solder flows better, easier to store not frightened about knocking it over and spilling it, like water based, wish I had found it sooner.

For the past 40 yrs I have used 'Water soluble Aqua Flux'. Read about this Paste Flux and gave it a try. I find that I do not have to apply so much and the solder flows much better.

Took a chance because I’m sick of liquid flux and this paste is so so much better. I don’t think it’s the “standard” paste flux used for stained glass but it absolutely works. There’s no popping, it distributes solder like butter. Cleans easily and with the size of this tub it’s going to last forever. Tested it out on some glass globs and I can’t believe the difference. Solder looks clean and smooth, much less to clean off from the burned liquid flux. 10/10
