Stick to the two coat-method if you can. The results are far preferable.

|An overview of the four steps to white power armour.|
Step One: Undercoat
After thoroughly cleaning and basing your miniature, apply a white undercoat. Be careful to clean away any flash and mould lines as best you can before applying the undercoat. Once it's applied, check for mould-lines again. It's fairly easy to miss mould lines when looking at bare metal, but the undercoat can help reveal any you've missed. If you look at the example miniatures sword hand, you'll see that I missed some flash prior to undercoating which I caught and cleaned up afterwords. It's preferable to use a spray can or airbrush to undercoat, to obtain a nice smooth coat. The reason for all this meticulous cleaning becomes apparent in step two.

Step Two: ShadingWash the entire miniature in Black Ink. I use Games Workshop's Badab Black for this step, mainly because I can't reliably source Secret Weapon Inks where I live. Don't be stingy with your ink. You want plenty of black ink in every recess of the armour. If you've still missed any mould lines -even very faint ones- by this point, the ink will make them very obvious, but there's still time to clean them up. If you don't catch them now, your mini will look pretty awful regardless of how good the finished paint job is. Take a look at this guy's helmet, you'll see what I mean.
Step 3: Base Layer (x2)Now take your off-white paint ( I thoroughly recommend Vellajo Model Colour Silver Grey. It's so close to white that it actually appears white to the naked eye until compared side-by-side with a true white) and apply a base coat to all the white areas on the miniature. Be careful not to get any paint in the recesses. Use two thin coats rather than a single thick one to obtain a nice, even finish. Use a brush one or two sizes smaller than you would normally use when applying a base coat. It makes the process all the more fiddly and time-consuming, but you'll end up with a nice, neat finish.

Step Four: HighlightsTake your "pure: white paint of choice (I normally use Vellajo Game Colour White or Vallejo Model Air White) and highlight the raised areas of the miniature and the edges of the armour plates. This photo was taken at 7am this morning, so the lighting isn't what it could be. The best place to see the contrasting highlights on this marine is to look at edgeing of the shin plates and the hand holding the grenade. You'll see that the Silver Grey isn't as pure white as your eyes and brain were telling you, and the white highlights are clearly visible. All you have to do now is finish painting the rest of your mini.
