Balistol is not intended for long storage protection. it is a gun oil, cleaner and patch lube. It is outstanding when used for its intended purposes. If you want long term storage protection, use something like Birchwood Casey Sheath. Folks make the same mistake with WD-40. It is not intended as a long term storage protectant. Actually, it is simply a water displacement product for which people have discovered other uses. The "WD" in WD-40 stands for water displacement.
When used for their intended purposes, these products work great but don't expect them to do something for which they are not intended. In the same way a mule will pull a plow all day and a cow will give good milk, you could use a cow to pull a plow and you could milk a mule but it is best if you use them the way they were intended.
Balistol is great stuff, I use it all the time as a patch lubricant and cleaner. I also mix it with melted bees wax to make a great bullet lubricant but for long storage, I use Birchwood Casey's Sheath.
I wanted to see the rest of the quote that you gave in regard to alkalinity but could not find the website that you gave. I searched the
www.balistol.com website but they had no such quote there. I also looked at the Balisol MSDS but they made no mention of alkalinity. I would really like to read what was said with regard to any alkalinity of Balistol, would you please send me the exact site where you found that statement?
