this is a new 870 and i believe the finish is parkarized.
I use a product called Firepower 10 (FP-10) and it does the job of protecting the metal. Smells great to.
The only thing I use in the shop is Eezox. I have tested it in many ways and it is the one as a lubricant and rust inhibitor. We will probably supply a sample with all our products soon, it's that good.
You might want to check the corrosion tests I posted. FP-10 (if it is the same thing) is a great lubricant, but a very poor corrosion inhibitor. BTW, I also use it, but only as a lubricant, not as corrosion protection.
You mean FP-10. The formulation is no longer the same as it was developed originally. The inventor had moved on & is now behind the Weapon Shield products - his latest incarnation of a CLP. I started using Weapon Shield oil & grease about a month ago - ordered directly from the factory in the US - but it is still too early to tell...I swear by it. It shields against corrosion & stops and inhibits rust so the label and my own testimonial. It also smells like Cinnamon.
I use a light coating of CLP after every use and I find that it provides great protection.Hey guys today i was out shooting skeet when a downpour decided to roll up on us. we finished the round i lightly and quickly wiped down my 870 express, i like the challenge of a pump in skeet. so i boxed it up and went to the indoor range and shot pistol and rifle. As soon as i got home i opened up my SG case and my 870 was covered in rust....COVERED!!!!!!. i detail stripped it wiped it down cleaned with solvent and a coarse tooth brush because some of the spots wouldn't come off and oiled it like crazy. Is there anything i can do to prevent this iv heard of baking in Vaseline? please help this is a new 870 and i believe the finish is parkarized. Thanks alot.

Parkerizing is a electrochemical process that bonds micro grains of manganese or zinc to the bare steel after heating in a phoshporic acid solution. Aside form a nice color, the purpose of the micrograins is to suspend oil against the steel preventing oxidization. If the parkerizing holds no oil, it will just as easily fill the spaces with moisture - and rust. Parkerizing needs oil for corrosion resistance, it does not offer protection without oil suspended.
If the parkerizing was left dry without oil and gets wetted/loaded with moisture, it is best to displace the water with WD40, a warm hair dryer, heat gun or some other means before replacing the oil protection. Bottom line is the parkerizing needs to be kept loaded with oil maximize protection like others have mentioned.
