Waterproofing the Chip: Starbrite, Spray-on electrical tape?

Hello everyone,
I've made a couple of DNA mods, but the first one shorted after a couple months and the second is a work-in-progress. It's not that hard to solder up everything and get the DNA working... but, a bit of rogue condensation killed my first DIY mod, so ever since then I've been trying to waterproof the entire thing. I know it's impossible to totally do that, but I'd like to get as close as possible to maximize my mod's lifespan. 

I was wondering what you guys do for this? My plan so far is I've sprayed liquid elec. tape through the enclosure's interior, and I'm going to put on the starbrite on my solder joints. Still using heat-shrink of course. The actual manual says the chip has a coating and doesn't need any kind of epoxy or other coating... but, I've shorted once, don't want to do it again. Is it fine to coat everything but the heat sinks?
