the quickest and cheapest is the can of anti-spatter , i have a very good mig machine, Millermatic 200 and it will still spatter on some of the surrounding area . I run it with the gas at around 40 psi. for things that I want to keep clean. I use the 25 -75 mix, I may start using 100% argon. The spray works well and I also spray the nozzle inside and out to prevent any problems with spatter in my gun. It works well with my stick welder too and we all know how that is. The stuff i buy is in a red can , I do not know the brand but it is good stuff. Some of this stuff has a very bad odor. This does not at all. Good stuff ........ Red Can Anti Spatter ....... Good Luck .......
