By the time you rattle can it just buying the materials from
www.automotivetouchup.com will run you about $75-80.
Spend twice that and you can have a pro body shop spray and mount it same day. I always leave painting to the pros. They will use a 2K clearcoat so it will be durable as well, not to say you won't ever get a chip or two but its the nature of the front end anyway.
If you want to go wild you can wrap it in clear vinyl after paint but that will probably be at least 100 bucks extra.
