I painted my dart the first time with tractor implements paint it was cheap (18 a gallon in 2004), it didn't last. It looked really good at first but faded quickly. It looked ok for about 3 years and then started fading. By 8 years old you wipe your hand across it and turn your hand black now 15 years later its transparent you can literally see the primer. I have a before pic somewhere i will have to find it!! But here is a after pic. That being said however I think rustoleum is a much better paint than the 18 dollar tractor paint at tractor supply.
