JR Xs3 Not for Boat use!! no warranty!!!
I found some dielectric lubricant that's sold at auto sores on the web last night.
Has the exact same properties as this Aeroplate (waterproof, dielectric lubricant, safe for circuit boards and plastics) but without the hobby level price gouging.
$6.99 for 16 ounce spray can at the auto site opposed to the horrendous $12.99 for 2 or 4 ounces of Aeroplate. I thought this stuff was some new product and turns out it's the EXACT same thing sold in auto shops for coating plug wires, distributor caps, etc from water. And it has been made and sold for 40+ years now.
Isn't it wonderful how the hobby sellers always take an everyday product, label it "for R/C use", and then stick it to the consumer.
