I had some tools that got wet and started rusting, this stuff really helped clean them up so I use it on any kind of metal that’s exposed to humidity and moisture.
Sprayed my lock on my trailer made them very smooth
Bottom Line
Yes, I would recommend this to a friend.

Outstanding Rust Prevention and Metal Protection

I use MP For a number of applications. My favorite and most important use is on exterior metal protection on firearm barrels, and other exterior metal parts. this is the absolute best product for this use, much better than ny CLP's. It also does not discolor the parts being protected and seemingly lasts forever in storage, while not interfering with the operation of actions, cleaning or other maintenance. Basically, any metal requiring protection is THE place for this product. I have recommended it to several other folks for use on their firearms. For heavy duty use for outdoor applications, where a light yellow tint or color is not problematic, I use the HD version of the product
I wish Canada could have the large bottles, but I love this stuff. I use it each fall on the undercarriage of my Jeep Wrangler to resist rust! It works great at protecting the frame and all the components. My mechanic loves the impact it has on protecting my vehicle, and he says it keeps the bolts from seizing up.
I've recommended MP to many of those follwing my audio repair workshops. One tech once told me, there should be a Jesus picture on the MP cans as it does miracles (with all due respect).
Aside from using for the obvious, car, home. I use it mainly to deoxyde electrical and electronic contacts and potentiometers in audio gear. A light spritz in controls and they become good as new. When I think other audio techs buy a lesser "professional" cleaner at 4 times the price which is not lasting, well...
I've tried countless products. MP it _the_ one for me, and also all techs following my workshops now !
Thanks Amsoil.
I work with telescopes and mounts.
There is a lot of metal on these that need to be protected.
The Amsoil not only protects the metal, but it also cleans
the metals for me.
Bottom Line
Yes, I would recommend this to a friend.
