WH40K - How to paint Power Weapons

Hey guys! As some of you know, i've been working on my plastic converted Vanguard Veterans, and they all have power weapons, so I snapped some pics of a power axe I was working on, and made a guide on how to do awesome looking lightning. Enjoy!

So, base the weapon with chaos black.
Next, basecoat the lightning area with thin layers of regal blue until uniform
Paint lines of enchanted blue in sharp random directions to represent lightning
Go over the enchanted blue with a thinner layer of ice blue for the lightning.

You're done. Enjoy!
