Chip Quik SMD FLUX NO CLEAN FOR APPLICATIONS, 10ml, Non-Sterile, Plastic Syringe

Will this work well for leaded soldering or is it only for lead free solder?

Is this item good for jewelry making for copper and silver, and did it come easy, medium and hard??

Would this be enough flux to replace a retimer ic on an xbox one x motherboard?

Is it possible to refill the dispenser with more flux?
