I wanted to seal several PCBs from not just water and general contamination, but from stopping the solder being a problem to anyone as I had needed to use solder that contained lead for these.

I searched for "conformal" coating and read the reviews - This seemed an excellent choice and yet again, the reviews saved me so much time and wasted money as it works perfectly. Yes there is a strong solvent smell and it is highly inflammable as it dries out, but that is normal with all conformal coatings and cannot be avoided as it needs fairly aggressive solvents to dissolve the plastic the coating is actually made of.

The real test is durability, even with a single light coat, the boards have all come out perfect, with no problems I could see, even using x30 magnification on the PCBs.

I don't know how it compares to other brands price-wise, but does it matter? One single vulnerable PCB will cost you a lot more than you could ever save (unless you are running a production line)! I am staying with CRC now as it has been better than other brands I have used before.

This stuff Works great! I mill my prototype circuit boards out on my CNC mill and for testing purposes I usually don't need to worry about any sort of coating or weather resistance.
Well I needed a way to make some of my circuit boards water resistant for testing outdoors (these control a series of solar panels)
and this did the trick, I sprayed a couple layers on each board, It goes on thick and seals up around the larger components.
I tested it by powering one of them on and dunking it under water. It continued to function properly and I am very pleased with it.

Use this to seal all circuits boards ESC's, receivers and even the case of my servos in my RC vehicles and boats. Even when there submerged for several minutes still work without a glitch. In my opinion beats anything on the market and saves money in parts.

Just what I needed for sealing cracks along fan vents on top of rv. Works well and no more messy caulking for me.
