You wont find 2 pack paint in an aerosol can I'm afraid. It's called 2 pack / 2k because it's a 2 part paint (base and catalyst) and needs to be applied with a spray gun. It also contains isocyanate which is very hazardous to your health. It's strictly the stuff of professional spray booths and the operator would normally wear a pressure spray suit with breathing gear. It's unsafe and probably illegal to apply at home.
I've heard of acrylic being applied over 2k primers but I've got no experience with it myself. You could always ask a paint rep. If you're going to use a 2 pack primer, you may as well use a 2 pack base coat and clear. It'll be more durable and less work.
If you're painting at home, stick to enamel or acrylic
