The surface area of the hood is difficult to do with a can. Smaller pieces you can get away with a can. I would pay a pro to do the job. By the time you get a gun and all you need for supplies you will be close to paying someone to do it. I have the equipment to do a vehicle, but understand the limitations. I did do a hood and roof with a Dip Coating and my Accuspray gun and that came out nice.
