SRA Solder 135 Rosin Paste Soldering Flux for Electronics, No Clean Flux Made for Lead and Lead-Free Solder Circuit Boards and Copper Electrical Wire - Safe Residues with No Goopy Mess (2oz 2-Pack)

I used one of those cheap fluxes and boy oh boy what a difference! However it's best to use it by putting it first into a syrnge equipped with a hollow needle of about 0.7 - 1 mm inner hole diameter. That will help immensely with the application

Very Good

This is my first time working with rosin. It did work beautifully! Don't know how I ever worked without it. This appears to be a quality brand.

Used for soldering cleaning of tip that works well.
