Fixed a small leak in my HVAC system. After completely rebuilding my R410a system and purging with nitrogen before brazing, I had a consistent pinpoint leak in my evaporator and Sil-Phos didn't plug the hole. After three repair attempts using high temp Sil-Phos and Oxy-Acetylene solder I bought this low temp silver solder knowing it would not damage the silver solder already applied to the wiring harness. "Painted" the joint with flux (it's a liquid, not a paste) and applied silver solder with a propane torch. I really applied too much, but it worked. After being tested with nitrogen at 100psi for 2 hours it held up perfectly. It's been almost 1 year and a recent bladder test of all joints showed they still have no problems.
