What king of spray paint is good for a cabinet?

I would be cautious about using anything except real wood if you are going to use it daily due to washing it often and the chance that it may swell. If it is for a decoration, that'd be OK. Normally, you do not find cutting boards painted due to knife marks.

Rustoleum is really good. I've tried Krylon, but feel that it goes on spotty and uneven.

If you're going to make a cutting board that you are going to use for food , you must find a food grade paint or sealer. As Sal85902 said, there will be knife cuts in the surface and that could introduce bacteria into your food. Having said that, Sal85902 also said if you're going to use it just for decoration painting would be okay and I agree. Best of luck on your project.

Rustoleum paint :)

Rustoleum should work well for you!

I am going to only paint the cabinet and not the top. I am going to buy a cutting board for the top. Thank you for all your help.
