All kidding aside, I'd rather not experiment, I'd much rather hear from someone who has used either. The product from Cosmoline Direct has one seemingly great advantage - its minimum melting point is 162 degrees F. Brownell's Rust Veto supposedly has a melting point between 140 - 170 degrees F. A temp of 140 degrees is a temperature that I think would not too difficult to reach inside an above ground enclosure that is not airconditioned like a storage shed or locker in pplaces where the ambient air temp reaches the 120's - that is somewhat of a concern.
Not really, but most of the guns it is on are.
I look at it this way: Cosmoline is a tried and true product that I know works. I also am quite familiar with getting it off of guns. Anything that has come out in recent decades has not been proven to be as good or protect metal as long as far as I am aware. So, if there is a product that claims to be the same thing, I'd rather buy it than spray on stuff or goop about which I have no clue as to its efficacy. That's the thing about being an old fart - going with what has worked virtually forever. I have the "If it ain't broke - don't fix it" mentality.
I would consider some of the lanolin based anti-corrosive treatments if I had trouble finding Cosmoline.
Brownell's has the stuff that melts at 140 degrees, the other place I mentioned says their product (wich they calim is the same as WWII grade Cosmoline) melts at 160 something. I am thinking of going for that one but am hopeful someone has experience with one or the other.,
That's what I was thinking as I was reading the posts.
