Yes, I read the same article several months ago. I'm not buying it. I have been using the cool-amp goop for > 20 years now, with excellent results. I have used it on tubing tank coils, loads of copper straps, and also items like relay contacts and contactors etc. After applying the cool amp goop, then rinsing, then drying...... u barely touch the probes of the HP DVM on there...and it's all 0000's. And it stays like that after years of use.
Why do u think telco's and power companies buy it ? It's used where buss bars overlap and are bolted together. BUT the copper to be plated with the cool-amp goop....1st has to be properly prepped 1st. And that means beyond squeaky clean. Then all holes are drilled / punched, then the piece is re-cleaned. Then the cool-amp goop is applied. It's a powder that I buy from them in 8 oz jars. The correct amount is dumped into a new clean small plastic container ( 2" diam x 1.5" high)..then just a few drops of water added, then mixed. It has to be the right consistency, so it feels...'granular'. Then I get in there with my bare fingers and apply it, and rub it on really good, doing the same piece over and over. Any excess is applied to the next piece to be done. 1st piece is then rinsed in warm water, then tamped dry, and thoroughly examined under strong light from every angle. I typ do several pieces all at once, like a mini production line.....at the SS kitchen sink. The cool-amp goop has an indefinite shelf life. What I haven't tried..yet is their 2nd product, called...'conducto lube'. It's 100% pure silver, ground up. and mixed with I think in castor oil. It's used on contacts of relays, contactors, and also anything that has sliding contacts. Kintronics labs uses it on all their roller inductors, like the actual coil, and the pulley that rides on the coil..and also the shaft that the pulley rides on etc. Plus end shafts. And also the sides of edge wound roller coils. I started using the cool-amp goop, simply cuz I hate the look of bare copper, but that's just me...esp after years of bare copper, and it tarnishes. BUT if the connections are solid, and that's a big IF..... the rest of it can tarnish all it wants. Also, there is copper, then there is copper. The OFC type (oxygen free copper) is the purest you can get. OFC is used in welding cables, and stuff like the plates inside Jenning's vac caps, both glass and ceramic. OFC is also used on Eimac external anode tubes, then silver-plated.
