Oatey30013 Paste Flux, 4-Ounce, Yellow

I do a lot of my own maintenance on cars and motorcycles and have never been particularly good at soldering. I read online somewhere that solder flux or paste makes a big difference, and I ordered this one just because it had positive reviews on here. It makes a world of difference, and has made soldering a joy be it stereo wires or throttle cables. I can't compare it to other similar products as this is the only one I've ever used but it works very well.

I am new to soldering, so I don't have a lot of experience, but this is working very well for me. The paste flux has been much easier to use than the fluid/gel kind and for my purposes (jewelry), this tub will last me for a long, long time.

I made the mistake of using this on electronic circuit boards and found that the residue causes shorts. This is however a great flux for attaching larger pieces of metal together such as pipes or for soldering big wires or buses that do not have any nearby active circuitry that you can thoroughly clean in water and you want to ensure a strong bond.The improvement in solderability is quite noticeable, It is a little hard to just apply a small amount of the flux though or precicely apply it without spilling to other areas. it tends to goop and form "peaks" that fall over onto adjacent parts, so it should be used for large welds or brazing that you can clean afterwords.

This tub was cheaper than the two ounce tin can. I refilled my can and still had more than half left. The flux works very well. I have used it for 40 years.

To solder copper waterline fittings. The size is a joke. I understand this is a manufacturer thing but Amazon miss represents the item.

yes, this product reach my expectations, thank you. the only problems was that I ordered the incorrect size ,but every thing with the cuality of the product was excellent. forward I would like to ask for another one. but a big one.

if you're frustrated by brittle, charred solder joints, or unable to solder to a PCB pad, flux makes all the difference in the world. Keep your iron clean and sharp, your connections stronger and more reliable. And here you get a lot, for not much money. Very happy.

Always makes a very nice and clean connection. I tried it with out using the flux and its very rough to do, but with the flux everything flows nicely.
