Care is needed in selection as some coatings are partially conductive.  Servisol Plastic Seal 60 is good high-voltage lacquer (don't get it near switches, display panels, etc - it'll wick into any small gap).  For temporary use.  CorrosionX oil-based is also compatible with electronics.  Engine marinisation guide is HERE

Thanks, the Servisol is exactly what I'm looking for.

If you want to go the whole hog and pot your board then this stuff is pretty good.

It doesn't have a shelf life and you can easily dig your circuit board out should the need arise. I dare say it's a little shock absorbing too as its quite soft when set.

Interesting stuff, must check to see if it's available locally.

The gel arrived today, I hope to get a chance to try it out later on some small parts.
