Prip's Flux 4 oz.

An instructor recommended this flux and so I bought it but expected it to be like other fluxes. It took me a while to use it effectively as I was used to putting the flux on cold metal. I gave up for awhile and then went back and worked at it again. It clearly works better than other flux. It prevents fire scale and the solder melts more quickly. I will keep on using this in my jewelry making business.

Does what it says. Protects, reduces need for clean-up and helps non-paste solders stick as you prep your soldering target. Pre-heat your intended solder area and spray on lightly. Sprays very easily without clogging. Buy the bigger bottle. This stuff goes fast, especially if you do a lot of soldering.

Struggled with different types of fllux and then used this product. I use almost 98% of my work and would not be without.

Great product

This is the best flux for copper and brass. The solder just flows so quickly and smoothly. I don't use it on sterling or fine silver.

Best flux for copper!

Works great on most metals

it took a long time to figure out how to use it. A lot of time searching the internet. Needs to have better instructions.
