Understandable!! [:)]
Sweets is pretty awesome stuff that doesn’t give much room for carelessness!! By all accounts, it will corrode a bore if left too long.
Still, while I could care less about brass marks on an AR deflector, I occasionally use Sweets to remove marks on handguns where I’ve used a brass punch to drift sights. I’ve never had a problem, and the marks disappear almost instantaneously!!
Incidentally, in my experience, Sweets doesn’t seem to do much in my AR bores (possibly since they’re pretty well made, chrome plated, properly broken in, and well maintained to begin with).
However, I find it’s truly fantastic in larger, unplated rifle bores, especially of military rifles.
It also does a great job of clearing out my sinuses!! [:D]
