Under $100....
Well, you MIGHT be able to get away with that if you spray it yourself. You might be able to get a pint of Acrylic Enamel, and the reducer and hardner for that. Most acrylic enamel systems do not require the use of hardner, but it makes it MUCH more durable, and if you do not use the hardner, the finish may be ruined by solvents such as carb cleaner and gasoline.
Some of the bigger paint shops have a machine that can inject the mixed color into spray aerosol cans. Expect to pay about $25-30 a can. Two or three cans should cover the hood well. Remember, this would be automotive paint, and not your typical Krylon bought down at the local hardware store. So it will go on MUCH nicer, especially if you keep your edges of your spray pattern wet, and get uniform, over-all coverage. You will not be able to tell if it came out of a gun or a can if you do it right.
It is all in the prep work. The more work you put into the prep, the nicer the end result. Don't expect to scuff the hood with 80-grit, and spray the hood in a dirty shop and expect awesome results. Spend alot of time sanding, using finer and finer paper. I would start with probably 320, 220 if there are deep scratches, and then work up to 320, and then 400 for final sanding. With most Urethanes, I finish sand with 600. These are all wet-or-dry sand papers, using water while sanding. Wash the hood with hot soapy water when you think you are done, rinse it well, let it dry thoroughly, tack-rag it off, and spray away!
Piece of cake!
