Slightly behind on my painting...

So, how can you tell you are slightly behind on your painting? When you have to use an entire can of Chaos black undercoat and you still have not finished! For the record today I undercoated:

• 3 Drop-pods
• 7 Rhinos & Razorbacks
• 1 Predator
• 1 Bastion
• Assorted turrets, guns, emplacements and tank parts

It does not sound like a lot, but it is a lot of square footage of plastic to cover. Right, now to make it blue...
