Electrical components have been protected with "Glyptal electrical varnish" for many years. Caution do not paint the heat sink on your ESC. Water and electricity are a really poor combination, The use of lots of silicon spray and grease are a good tool. Plugs, switches and even some wire will get water in them.

Re: Electronic waterproofing

If you are going to use silicon sealant to waterproof your electronics, be careful. There are two types of silicon sealant: Acid cure and neutral cure. Never ever use acid cure. Most bathroom type silicon sealant is acid cure! If it smells like vinegar, it is acid cure. Make sure the package says "Neutral cure". If the warnings on the package mention acetic acid, it is NOT neutral cure. Acid cure silicon sealant will leach acetic acid which will eat away at the copper traces and any other exposed metals.

Re: Electronic waterproofing

Really good tip, Jim. This never occurred to me though it very well should have! I am intending to do just that and I KNOW the silicon sealant I have is acid cure.
