It is interesting but probably is a permanent solution, i.e. if you're the type who modifies the board often, doing a lot of soldering components, maybe this product isn't for you.
I'm interested to order and apply it to the HL electronics and see what'll happen....
Here's the link to the product itself: http://www.spillcontainment.com/ever-dry
Anyone here has heard of this stuff?
ETA: ACK! Apparently it is NOT available for consumers at the moment. Sorry guys.
