Deoxit???

I'm building a pair of loudspeakers that are intended as heritage cabinets which I hope will outlive me (at least as furniture). I'm paying great attention to crossover assembly, internal wiring, etc., but at some point I'll be sealing up the boxes (although access will still be available by pulling the drivers). I've heard that Deoxit can be helpful in deterring corrosion. I'm not familiar with Deoxit other than as a spray-on contact cleaner...does anyone have any experience with it as a corrosion preventative, and are we talking about Deoxit Gold or something else?
Thanks!
