870 express rust

I wanted to get a 870 express tactical as well, then I saw the 870 magpul edition with cerakote, the finish is awesome, how is this kind of finish in preventing rust?

cerakote is the best spray on firearms finish on the market today. It's the gold standard. It's hard to get a hold of it in Canada though, or at least used to be. I'm starting to see shops offer it here now. I've had several knives coated with the stuff, and it is incredibly durable.
 
I think there's a couple cerakote dealers around Canada now and there's plenty of applicators. Its available but it might take a little googling to find the nearest dealer.
 
I'll add that I recently bought an 870 Express. I've only been out with it once. Checked on it 2 weeks later and it had quite a lot of surface rust. How disappointing. It cleaned off but I'm sure I'll have to recoat it.
 
Everything non-stainless of mine, except antiques and some customs, go to murdoc (Barret Arms) for bead blasting, Parkerizing and Arma-coating. No worries of rust and a nice looking, durable finish.
 
Interesting. I treated my 870 Express with Frog Lube when I first got it. I once left it uncleaned for over a week after an evening of trap games. Shot 125 rounds that day. No rust what-so-ever when I took it out again more than a week later. I guess I better clean it right away next time. Dont wanna take the chances.

There are a few exhaustive corrosion test vids on youtube and elswhere.

Frog Lube is consistantly in the top 2 performers.
 
The finish Remington uses should be banned. Higher end shotguns do not have this issue. Keep it oiled religiously or refinish it.

Salt creep is the result of residual bluing salts left on the metal being blued, and it shows up in the form of powdery to crystal-like brownish residue. It happens when the neutralizing process is incomplete, usually due to haste...no prob, just keep cleaning, oiling, and it will soon be a memory.

I was so worried about the brown residue on my new Police Magnum, that I gave it a bath in hot soapy water, then flushed it with water displacing oil (horrors, yes it was WD-40) then cleaned with Hoppe's as per usual. Oiled it up, and never a single little pill of salt showing up after that.

I have two 870s with the express receiver. I have noticed that if neglected, in other words not oiled and given a good wipe regularly, I will get small rust "pimples" here and there.

A friend reccoemnded Balistol as a good product to keep the exterior of the gun coated with. I tried it and love it. IMO is seems to leave a better film/finish after wiped off. Every time I get back from shooting either gun I give the exterior a good wipe with a Ballistol wetted patch and then a wipe off with a clean rag. Have not had any rust issues since.

I have never tried Frog lube but it sounds good too. G96 or whatever oil is better than nothing but I think the Balistol leaves a a better and longer lasting finish.
 
Hey Noob~you're lucky it was an inexpensive shotgun you learned the lesson with. I've seen guns costing 5x more than an 870 Express with permanent fingerprint marks on them from not being cared-for properly. I have several, vintage Remington shotguns from the "good old days" and in spite of the level of polish/deep blue they got from the factory...they'll rust too if put away wet. However, I'll never know...because I baby these old girls. :)

Basically, I consider moisture and sweaty fingerprints to be the 2 worst things for a metal finish. Never put away wet, and if the gun gets really drenched...I tear it down completely, wipe down...air dry..then re-lube and reassemble. Maybe there is a better way, but my guns mostly look like the way they did when I got them.

If your gun in kept in a very cold house with a/c in the summer, be mindful when you bring one of them straight out into the hot summer air.
(think of a cold can of pop taken from a fridge and placed outside on the deck...)

lol. Fridges are 4C. Who is cooling their entire house to that temp?

My basement is about 16C all summer. My guns dont sweat when i take them out.
