Phase 1 Introduction - Vindicator

Starting to paint my Vindicator, it is currently on phase 1(beginning haha), as some of you know that I owned a "Black Templar" Vindicator, so I take it as a looted tank by my new Chaos army!, so what I need to do is to base it black all over again, will paint it regal blue. I would love to paint it slowly for I'm currently looking for some useful videos in U'tube on painting tanks, a friend gave me an airbrush before he migrated to Australia.... hope I can make a good use of it soon, :)
