So, What do you guys use to prevent "sweat etching" your CCW?

I've got an airlight i keep in a thin leather deep IWB conceal for work (outdoor warehouse, thin clothes) and it's started to pick up pitting from the gallons of sweat i pour through the poor thing. How do i coat it without causing myself a large rash? Thanks dudes. via /r/CCW https://ift.tt/2NsrwXk
