Of course, the problem with epoxy is that it is a tad on the perrmanent side. If you screw something up, or if, say, the antenna wire breaks later, you have little hope of repair.
With Scotchkote, it purns offf with a soldering iron when you unsolder - easy to repair through.
Some of the specially designed silicone conformal coatings http://www.altex.com/MG-Chemicals-S...43193.aspx should work well, too, but I have not tried them (I have a couple of botles, but have not felt the need to try them whan Scotchkote works so well). With the Silicone conformal coatings, you will want a blacklight to check your coverage (many flouresce just for this purpose) - with Scotchkote, you can easily see what you have covered. I am not sure how well these hold up over time, and whether they may possibly delaminate like Liquid Electrical Tape.
There is also Acrylic conformal coating http://www.altex.com/Acrylic-Lacque...43194.aspx which should work decently, if the surface is clean, etc.
Nice thing about the Scotchkote is that it agressively bonds without cleaning the surface, remains flexible(ish), and does not delaminate. And is easily repairable.
