QMaxx, The Gunsmith's Choice to Protect Against Rust and Corrosion

Updated: Jul 8



Jim Green is a Marine Corps artillery combat vet. He served in Desert Storm, which is about the sandiest, grittiest place on earth:

I’m highly sensitive to the dirt and grit that accumulates in gun actions. So when I’m asked about gun oil, I respond by spraying a little QMaxx on my fingers. Then I rub my fingertips in some dirt and invite my customer to feel my fingertips. There’s no abrasive feeling. I repeat the process with another brand of gun oil, and they can feel the grit that always sticks to my fingers.

As a certified master gunsmith and owner of Downeast Gunworks in Milbridge, Maine, Jim’s equally familiar with the rust and corrosion that rain, snow, humidity and fresh and salt water can cause:

The biggest part of my business when I’m not building custom rifles is cleaning. I get firearms whose guts haven’t seen the light of day since they left the factory. Inside I find years of accumulated carbon build up, dirt and even pine needles. Every gun leaves my shop with a treatment of BLU or Black Diamond because it may be years before I see that gun again. QMaxx gives my customers’ firearms a little extra protection.

Water is No Match for QMaxx


Maine’s a wet state. Rain, snow, lakes, streams and miles of coastline mean rust and

corrosion is a serious problem. Jim reflects that some of the guns that come into his shop look as though guys had been paddling the marshes with their guns or just left them sitting in their canoes for weeks.


The worst gun, however, was Savage Model 24 with a .30-.30 rifle barrel over a 20-gauge shotgun barrel. A woman brought it in, explaining that she’d accidentally dropped her boyfriend’s gun in a brackish estuary for a salt marsh. For two weeks they searched for that gun, and when they found it the stock was swollen and cracked and the action rusted shut.


“I wasn’t sure how much of the barrel and action I could salvage,” Jim says. But he worked on it every day. He heated the metal and sprayed it with BLU. The low viscosity helped QMaxx penetrate.


After about five days, Jim could open the action and pull off the barrels. “I used an old gunsmith trick. I buffed the metal with BLU and 0000 steel wool.” The BLU penetrated down into the pores of the metal, displaced any moisture and removed much of the rust and corrosion. He sprayed and buffed the internal parts, and ultimately only had to replace a couple of springs and the stock.


Putting QMaxx to the Test


The Marines have a lot invested in weapons oil for LAW (light anti-armor weapons) that’s supposed to be pretty good in extreme environments and especially harsh, cold conditions. Although it doesn’t freeze, the PTFE Teflon thickens and gets gummy.

To see how QMaxx ICE would hold up in a extreme Maine winter, Jim pulled the barrel and action off a Model 670 Winchester, sprayed it with ICE and jammed it in a snow bank. At the end of the day, he retrieved the parts, snapped them back in the stock and fired the gun. Perfect. It didn’t freeze or gum up.


Cumulative Benefits of QMaxx


“I’ve replaced all the gun oils and lubricants in my shop with QMaxx. And I’ve noticed that the more I use QMaxx the better the protection.” It doesn’t cake up or break down under heat and stress, and guns are easier to clean. Now that Jim is using Black Diamond on his black powder cartridge guns he never needs to run boiling water through them. He simply bore snakes the barrels, wipes everything down and sprays them with more Black Diamond.


QMaxx gun oils are this gunsmith’s Number One choice to fight rust and corrosion and reduce dirt’s wear and tear.
