So as I learn more about my gun and the general maintenance tools to use on it, I see some odd stuff around. For instance, no one I've seen (whom all seem like they've had plenty of experience in maintaining markers,) likes using dow55 on regulators, like slinky and even Latsabb. They refuse to use dow55 on BL regs. I'm just wondering, is there a problem with using dow55 with regs? Is there something troublesome about using dow55 on them? Or is it just preference?
