Thermaltronics TMT-FP-1 Rosin Flux Paste, 2.0 oz (57 g)

Works like a charm. Apply with a q-tip to surface where you want solder to adhere. Great for pipes or wires.

Nice tin to keep it clean a works very well.

Great!

Great product, performs as expected. The only thing I don't like is the can its packaged in. It's difficult to pry open. To make the task of removing the top easier, I used a flathead screwdriver to make a indentation in the bottom section of the can. I did this by: nserting my flathead screwdriver in between the top and the bottom sections of the can, held the can steady, and then I lifted up on the handle while applying downward pressure on the lip of the bottom can with head of the screwdriver. The bottom lip should have a "V" shaped indentation that will allow easy access to the flux.

The paste works as advertised. Makes soldering electrical wires much easier.

I’d been soldering for while without flux and super frustrated with the results. With a little of this flux, the solder flows so much better. You get a good size which will last a hobbiest like for years. It’s easy to apply and my soldering has improved substantially.

Convenient size and good quality soldering flux.

Solder works fine but the tin it comes in is awful. Sometimes it feels impossible to open
