How much paint?

[chriswood7]

Hi all,
I'm new to custom painting but I've just picked a spare set of tins up for my Sportster that I want to spray. Just a basic basecoat and candy job, my question is roughly how much paint will I need to order?
Cheers,
Chris.

I would think a quart, of each, unreduced, would be more than enough.
