Thin coats of ElectroniCoat look best.

Works best when you apply very thin coats and let them almost dry between next application. 5 min between each, spraying from about 10 in away. Cover all connectors and heatsinks with blue tape, otherwise you will regret it. We used this stuff in the military. Had to spray it outdoors as there is an odor.

Awesome

Great product

Helps electronics survive outdoor moisture

I use this to coat the circuit boards of my Eufy magnetic door sensors.



So far they have been through two rains each in Northern California and they are still working.



If they stop working I will report back and change the star rating.



It is an acrylic type coating, sprays on clear but dries somewhat opaque.

Great for older automotive electronics

Sprayed this on the circuit board of the ECM in my Fuel Injected Bronco. Moisture is the enemy of these old boards, and in an old vehicle, moisture is everywhere. Sprayed a few layers of this on the board front and back, so now my Bronco will run through any weather.

Easy to apply

Works as advertised. A bit pricey.
