Time to beat this dead horse again maybe. I keep reading so many posts from guys using nitrogen and brazing and have been long before I installed my first 401a. I was reassured by many people and sources that with correct techniques Stay Brite 8 was more than adequate. We all know brazing with a stick can cover up a multitude of sins.
I think I'll stick with Stay Brite but just curious of others views. Why especially are you uncomfortable using Stay Brite 8?
