I am looking to store some AR's as well. Sounds like there is little consensus on what product to use other than cosmo which can be a pain to deal with later.
I went to the Breakfree site to what other products they have and they appear to have many. Has anyone used Breakfree Collector? Here is a snip:
Collector Liquid provides a protective coating against rust and corrosion on metal to metal finishes; no need to remove before use.
- Developed for military use to protect weapons for up to 5 years in storage.
- Exceeds military requirements for rust and corrosion protection.
- Unique 100% synthetic oil formulation with multiple high performance anti-rust and corrosion
inhibitors.

oil.

protection on mild steel panels when exposed to 100% humidity at 93 degrees with out
developing even one micro of rust.
