I have an 870 Express tactical and its having an issue with surface rust. I know some of the newer express models have this issue and want to take care of it. Im sure I could bring it to my local shop and have it coated, but is there a product you would recommend for do it yourself project? The rust is not bad, but id rather not see this happening on a brand new gun that is cleaned regularly and stored properly. I know there is plenty of coating products out there...but what is your preferred method? Thanks!

In my opinion the standard factory rinse doesn't get all the bluing salts out of the rough surface. And then oil is not a solvent for bluing salts. I have solved a couple by giving the metal parts a good bath in hot soapy water, then rinsing, then drying, then coating it with RemOil and wiping it off. YRMV.
The new guns I have looked at recently actually have more of a true matte finish; smoother than previously. What could have happened... did.

I would try Virginian's method first...then, if that didn't work:
Try lightly rubbing with 0000 steel wool with a touch of oil...wiping away the slurry often...then re-apply oil and rub again until desired effect is achieved...touch up with cold blue if required. This is a real good alternative to the 0000 steel wool: http://www.big45metalcleaner.com/ http://www.big45metalcleaner.com/Works/ |

I've used a toothbrush with hoppes solvent..... Then apply light coat of CLP (guns I store and don't use).... The few I use a good bit, I wipe down with remoil after each use... I run 2 dehumidifier in my gun safe

Do those dehumidifiers drain water off somewhere? Just curious, don't know much about them. ![]() USMC 83' - 87'

The desiccant ones only absorb moisture, and need to be recharged - heated, driving off the moisture. Bluing salts also absorb moisture. The electric ones like a Goldenrod just raise the air temperature so you do not get any condensation on the guns. When my safe was in the garage 2 years in Ohio, I put a 40W bulb down low in the safe and no problems. The other 35 years when the safe has been inside the heated air conditioned part of the house I have done nothing.

One of them is in a canister, when it turns blue, I plug it in to a wall socket and it dries out. The other dehumidifier is an electrical bar. Bar heats up to cook off moisture, also maintains temp in safe If its up high, it's coming to the ground |

Be sure and use a heater in a closed safe as well as a desiccant dehumidifier. Moisture will condense out of the air onto an object that is colder than the ambient air. So you want your guns to remain warmer than the ambient air. 870 Express finishes are somewhat infamous for surface rust.

This definitely helped take care of the rusty look the gun had. Still interested in doing a coating whether a DIY job or getting it done by a shop. Going to take it to my local gun shop to see what they recommend. They are the ones who sold me the gun so Im sure they want to help their customers and their products. |

I know there are the usual companies out there, that offer coating kits. I know Dura does, I have seen the options on their website. They have some awesome camo jobs to choose from. USMC 83' - 87'

The only thing I have ever used was Rustoleum flat black back when I was doing a lot of salt water hunting. It worked.

My 870 express seems to have the same issue. I thought it was just neglect of the previous owner. I can wipe the barrel with rem oil every week and the rust comes back. I'll give these tips a try until the entire gun gets a new paint job.

Oil, Hoppes, naptha, lacquer thinner, none of them will dissolve any salts in the surface pores/irregularities. Nothing but water is a solvent for the salts. A little Dawn helps.

Well let us know their response.

Did not know this was a problem on the 870 Express with rusting. Some say caused by not removing bluing salts? Is the matte finish more susceptical to rust than the regular high polish cold bluing?
|

Yes, a rough finish will hold anything more than a smooth polished surface. Oil is NOT a solvent for salts. You can oil it forever, but until you wash the salts away the issues will persist.

Thanks Virginian. Have heard of parkerized but believe this finish is different if I am correct. Am a bit of old school and recall matte finishes were not the norm in my day. Took the high polish bluing for granted all these years. Guess it is more expensive and time consuming for the manufacturers. Boy times have sure changed. With the price of good figured walnut I guess synthetic and polymer are here to stay. |
