Honestly if you're just wanting to make it look a little better I'd paint it or get a skin for it. The PV that IG gold plated is worth alot more to begin with. I don't think it would be really cost effective or worth the time to do that to Ego equipment.
Would be a bummer if you spent the effort and money on it and the mofset went out on it a week later.
Agreed, an ego is not worth the effort or money to plate. You could
buy a new battery in whatever colour you choose for less. Or, you could save your funds to move into your first
mod, there are many great vendors out there to suit your tastes and needs. Besides, when you
buy cheap, you're only gonna end up buying twice. About how much are you wanting to spend? You might surprized at what's available.
