Engine Paint Question

The paint can just says to use the primer first but gives no suggestion, time wise, after that.
I guess that would imply that one must let the primer cure first then, as the primer can says to let cure for 7 days. lol

And that's probably when the temps outside are warm.
Put a bag over it to keep it clean,give it a day or two,and paint it.:glasses7:
