When I picked up my new Imperial Guard codex the other day I saw a display of GW's foundation paints. Having just painted two layers of basecoat on four Pacters I decided to give it a try even though it's a bit lighter than I wanted.
Here's one coat of Mechrite Red. Yes, one coat. It certainly does what it says on the tin.
One coat Mechrite red plus one wash of Devlin Mud.
And next to another Pacter painted with two layers of Vallejo's Gory Red followed by one wash of Devlin Mud.
I'll wait until it drys and put another wash of Devlan Mud on, but it looks like a winner to me. One coat will stop my already university-addled brain from frying like bacon. (Four more weeks!)
