Lower resistance at every connection.
Silver plating powder you rub on by hand, right in the field.
A damp cloth, a little powder and 15–30 seconds of firm rubbing. No plating tank, no electricity, no shop. Conducto-Lube carries the same silver into contacts that move.


Two products. One question.
Does the contact stay put, or does it move? That decides it. Some joints need both.

Every microhm at a joint turns into heat.
Copper grows an oxide film that resists current where surfaces touch. Silver's oxide stays thin and conductive. Joint heat = I²R, so the payoff grows with amperage.
Many joint compounds rely on zinc or graphite. Conducto-Lube carries pure silver, roughly 4× the conductivity of zinc, and works from −25 to 410 °F.
Repaired in place. About 100 °F cooler.
At a municipal water treatment plant, a corroded, hot bolted lug on a chlorine generation reactor was treated with Cool-Amp where it stood, with no replacement part, then re-scanned.
From the people who use it
Customer reviews · cool-amp.com“I have been using Cool-Amp to protect resistance welder connections from oxidation since I was the Welding Engineer at Chevy Gear & Axle in 1976. It is now specified by most automotive customers for all the secondary welder connections.”
“Saving contacts that have burned… put the lube on the blades & reconnected the circuit… saved myself a lot of money.”
“I was going to set up a plating bath. I didn't have to do that.”
“Eliminates chloride salt build up at contact points. Conducto-Lube protects the contacts from vapors.”
“Application can't be easier… I have tried tin plate and solder plate circuit boards but neither are as good as or easy as Cool-Amp.”
