I would never recommend painting the inside of a grill. Many here will cite issues with toxic fumes, and even the high heat paint makers say not to use it inside. I agree with this, although I know people who have done it with no obvious harm. I think after a long burn-off - and certainly after the inside is coated with grease - the risk associated with this diminishes substantially.
I will still say that the bare aluminum is safest and perfect for a Q or any cast aluminum firebox such as on a Genesis. That's how it is delivered new. I would, however, recommend washing it well after grinding and doing an initial pre-cook burn-off.
Doesn't the inside of the cookbox come coated with enamel from the factory, though? At least my Q300 did.
