Hello, Actually I have only used the Nano-Oil on two of my pistols, nothing that your other customers have not already done. I was having trouble with several new semi-automatics that did not want to feed correctly. I put a light coat of the “80” weight on the guide of the magazines and the ramp into the chambers on both of my new pistols. Now they are feeding with no problems. Amazing what the right lube will do. Thank you for making this product available to the general public.

I used Nano-Oil on two Benelli shotguns. I applied the lubricants as directed, WOW WHAT A DIFFERENCE. The action operates much smoother and faster, gave some to my two hunting buddies they were skeptical but after using Nano-Oil they had to admit that it is the finest lubricant available. Thank you StClaire

I just received my nano-oil and have already used it on my Kimber TLE it really does shoot smoother and cycle cleaner than it did with my other lube. I have also used it on some of my folding knives and found the same story there also. I really like the pin-point accuracy that this needle tip gives. It’s not messy and the oil goes right were it should. Good product! I ‘ll be in touch. Thanks again, Gary

I just built a pretty fancy folding knife this past week and used Nano-Oil on the pivot. This particular folder has a large blade and I was “pleasantly surprised” with the smoothness of operation using your product. I would recommend your Nano-Oil to other knife makers. Keep up the good work! Thanks, Scott

Great Product and Fast Service!My first use of the 10 weight nano-oil was on my old Swiss Army knife. The knife was frequently used on camping trips and had never been oiled in its 15 years of use. I ran the knife through several purges in an ultrasonic cleanser and applied the nano-oil to each fulcrum point on the knife. The resistance on the blades disappeared after opening and closing several times (except for the normal resistance that makes the knife function). I also applied nano-oil to the contact points on the scissor blades allowing them to open and close easier. The knife is in the same condition as when it was new, if not better.I also applied nano-oil to the bolts of a 1941 k98 Mauser and a Winchester Model 70. The lubrication of the friction points on the bolt made the action of both rifles smoother. I have not had time to fully apply or evaluate the nano-oil on the weapons, but the initial application shows some improvement already.

Nano-Oil Testimonial: ‘I was developing a threaded tailcap for a bare aluminum flashlight prototype & due to a slight threading mismatch, the pieces were on the verge of galling. Not knowing what else to do, I applied a small quantity of Nano-Oil and was amazed: not only did the parts mate markedly more smoothly & quietly, but all signs of galling were gone… and STAYED gone! I also had a problem with a sticky power switch on the flashlight which Nano-Oil fixed elegantly, I know of no other product so effective in these particular applications. I’m hooked!’

I have been spending some time looking for a better gun lubricant after a gun oil failed a shooter I was coaching while we were in Thailand this summer. She was shocked when I relubricated her gun and it “felt better”. I realized there is a complete lack of knowledge of what shooters should be using, and how a well maintained/lubricated gun can truly help shooter achieve better scores and help their pistol last.

I’m Brian Baleno and I first found out about your product through Scott Clawson. I had an aluminum flashlight with galled threads, by shear force I unscrewed it. I thought it was a goner but Scott put some of your Nano-Oil on it and threaded it back together. It came right back apart with minimal force, we wiped the threads clean and gave it another drop for good measure. It felt like a brand new light after that. That was 4 months ago and its still turning fine. Now I am the proud owner of your fine product, thanks for the great service too.I am please to write you and tell you that my experience with Nano-Oil has been great. While reluctant at first, I am convinced this lube is fantastic and makes a noticeable difference in the feel of my competition pistols.Nano-Oil Testimonial: ‘I was developing a threaded tailcap for a bare aluminum flashlight prototype & due to a slight threading mismatch, the pieces were on the verge of galling.

Malcolm in Missouri City, Texas. I have been using your nano-oil as pivot lubricant on my folding knives and find it superior to Mil-Tec, White Lightning, Royal Purple, and others. It is easy to apply with the pin point dropper and only a drop or two is required. Best regards, Malcolm

I used this nano-oil on my benchrest bolt action, I can feel the lift is easy. The Nano-Oil arrived safely across the big pond. I have already used it on my twist on/off flashlights and I must say even without cleaning off the other lubricants which I thought were good, you could feel the difference, quite remarkable stuff!

Wow received my nano-oil pen today, super fast delivery how did you do that in three working days. I am very happy with the pen, I have already put it to use on my swiss army knives and also hand cuffs both now operate a lot smoother,great stuff. Applications for this seem endless in my opinion. A couple of questions for you, can this be used on my flashlights ? also can I get extra nano-oil to refill my pen. Once again thanks for a great product and lightning speed delivery, super.

Thank you very much for the opportunity to comment on Nano-Oil 10 weight advanced lubricant. My primary application is my Kimber Eclipse Ultra II.45ACP 1911 pistol. This pistol has a persistent feeding problem owing to the steep angle of the ramped barrel and short frame design.I applied Nano-Oil to the barrel and feed ramp along with the Sear, hammer, mainspring housing, and slide rails on the slide and frame.
I noticed an immediate improvement in feeding with the lubricant versus RemOil® Teflon lubricant which leaves a sticky residue that Nano-Oil does not.I have also used a very thin coat of Nano-Oil on the pistol’s magazine which greatly improves magazine release and loading.
I have used Nano-Oil on several locks in preparation for winter weather and expect much improved performance.
I have also used Nano-Oil on several of my power tools (DREMEL®, Porter-Cable, etc.) and plan to use Nano-Oil on my Snowblower cables when I prepare it for the winter season.
