A pc cpu gets warm. Are metal detectors heating up? I modded a volume control in my ace250 the day I got it anyways so no warranty for me.
Anyways, I quote the reply I got from the american supplier. (Nanoflow X)
We usually have clients send in their products for us to coat but since you’re in Norway we can ship out a 50ml bottle of the solution for you to apply on your own. Would you be interested in something like this?
It will make your electronics IP67 rated which is enough to protect it from moisture build up and damages. The solution is $80 for a 50ml bottle. 50ml of the solution can go along way and protect many electronic boards you may want to have protected. The board you shown within the link should use about 10ml of solution. The solution is not cheap as it is a one of a kind solution. Once you spray it on the circuit board, you can take a water dropper after it has dried and see how hydrophobic the circuit board has become.
I doubt I'll go through with it but it's still interesting.
