Last night Todd and I watched the Privateer Press Core Techniques DVD, this looked like it would be a good intro for someone (Todd) who hasn't painted alot and is getting into War Machine.
The DVD runs 60 minutes and is $30 and is online on certain sites and stuff.. yeah.
It had a good basic into to prepping/priming (including using filler on gaps), supplies, paint mixing, and the 4 core techniques needed for doing quick good tabletop minis. The showed quick examples of how to paint a big robot dude, a lady in a red communist looking outfit, and a never blight monster thingy (rake?).
Edit: they also had a quick bit on basing, so yeah every step explained easily from start to finish
The four core techniques were the base coat, blending, dry brushing, and washes.
Not my personal style but a good intro to getting your minis tabletop ready and eye catching so you can play.
Painting minis is the best!
