I keep my guns lightly rubbed down with Hoppes and never really have a problem with rust. USP was spotless last weekend and within 4 days (1 day of 20 rounds) and keeping in the car, the top of the barrel and sights are rusting.
What am I doing wrong? |

I live in Florida and have never had a problem with my USP rusting anywhere  I have my USP45 Tactical in my center console whenever I'm driving, however I usually don't leave it there overnight. The only places I ever actually leave oil without wiping it off are the slide rails. That's very odd. I agree with switching to CLP, though.

Hoppes isn't known for rust prevention, IMO. Either switch to Break Free CLP or Gunzilla. Living in the humid South, one best give one's fahr-arms all the help they can, IMO. My .o2 +1 Hoopes is great for cleaning but you need to follow up with generous amounts of CLP. |

The night sites are common to show signs of rust. I think Trijicon used a bad batch for thier USP models. I would suggest the following for storage in a go bag or car. Strip the gun with solvent an clean it. Some older oil products actually have "water" in them. Take a deep soaking product like "Rig" by Universal and rub iit into the slide on the exterior twice. Take a thin mil of white lithium grease to the barrel on the outside as well as a very thin rubbed mil of it on the inside of the slide. Also distribute a small beed of the grease on the inside railing of the slide. Next apply small droplets of CLP to hammer mech, trigger mech and mainsring n the mag well. Remember not to allow the CLP and white lithium grease to meet eachother. They do not mix. Take a rag with a bit of armor-all on it and apply it to the plastic frame. The inside of the barrel should be cleaned with a boresnake that has a bit of CLP on it.
You should be set for six months of storage with the weapon. When inspecting the white lithium grease should turn a light brown signifying that the weapon has been exposed to moisture and that the grease is ready. To be stipped off and reapplied. Repeat the process at this point. This is an ideal combat ready applicaton for a polymer firearm....... |
