If you’re into radios and want a better connection, I’m going to give you some proof you need to use this product. I’ve been using it for awhile on my antenna connections as a ‘feel-good’ product because I’ve never been able to actually measure if it makes a difference. I would swear all my radios worked better but after today, now I’ convinced.Trying to install a CB into these new Cherokee’s is a hassle and I finally gave up and just went the mag-mount route. To make matters worse my Trailhawk has the panoramic roof so I have hardly any ground plane. Not expecting a lot in the way of performance but good enough to listen to while driving down the road, I ordered a Browning NMO mag mount since I like to switch between 2M/70cm and 11 meter. I installed the mount on the 6″ wide sheet metal I have left on the rear of the roof and ran the cable to my Anytone ‘CB’. For an antenna, while awaiting my Browning NMO 1/4 wave, I installed a NMO to 1/4″ adapter, 4″ heavy duty spring and a 2′ Firestik with a tunable tip. When I tune up a compromised system such as this, I tune the channels I’m going to use verses the 1 and 40 route. Checking the SWR got me a 1.5 or so on Ch 20 with which I was happy with so I was just going to leave it alone. Then I remembered that I didn’t put this copper antiseize on all my metal-to-metal connections. So tearing everything back apart, I gooped all the threads and center connectors and snugged it all back together. Checking the SWR on CH 20 one last time before calling it a day resulted in a 1. Dang. I figured I overdid it and shorted something so I removed everything again, wiped anything I felt was excess and reconnected. Still had a 1. Double dang. My meter must be bad. So after some checking I could not find an issue, hooked it up again and, yep, still had a 1 on CH 20. So I move to CH 1, calibrate and test. It stays under 2.5. Interesting. I go to CH 40, calibrate and test and, again, an SWR under 2.5. I switch to CH 19, calibrate and the needle doesn’t move. WTH? I thought something was way wrong until I received a RX from 19 miles away. Now I’m seriously shocked. I mean, this is a mag-mount with a 2′ antenna, which is already seriously compromised, and I don’t have much ground plane either. I just dropped to a SWR of 1 with nothing but some conductive grease and it’s legit!I’m sold. I will always have this stuff on hand for radio work no matter what. That’s my story and I’m sticking to it.

Used this for my brake pad replacement and applied thin layer where there is metal to metal contact. A little surprised to see that they changed the bottle labeling. Made me wonder if this is a counterfeit product. Photo of 1 lbs bottle has the word “COPPER” prominently in large font, all caps and copper colored, which I thought was a nice touch and would be easy to identify. Just below “COPPER”, you can see “ANTI-SEIZE LUBRICANT” in all caps. The 1 lbs product I received has a different label. Instead of all caps and copper colored large font, the one I got shows “Copper” in blue and font size is smaller, matching the smaller “Anti-seize lubricant” printed below. Made me wonder if this was legit. But I wouldn’t know since I am no copper anti-seize expert. Just have to trust Amazon on this one. Bottle was half full by volume. Did not weigh but going to assume it is 1 lbs by weight. Grease was medium/dark copper color. Happy to finally try copper for a few bucks more since I have always used aluminum anti-seize grease prior to this with no issues.

Good stuff works as intended so far

Easy to remove and use

Great item , works well for breaks !! Note tho, it seems like it’s ‘half full’ because the measurement used is wt oz not fl oz… One’s weight the other is volume, so I guess put it on a scale and see if it’s as advertised. Tho I will say I was hoping for the JP labeling :,(

Does a great job of preventing bolts and nuts from seizing up.

This is a lot of product! I purchased it for a few things I was replacing. After I used it I still have a lot left. The lid has a brush attached which makes it clean and easy to apply.
