Check out carquest, most stores have a full paint supply. Just get a gallon of high build sandable primer. (eurithane or lacure you decide). You can also get a pint of white sealer that they can "tint" so it will look like you have a color'd primer.
I bought a gallon of primer and gallon of reducer for $50. I did my Zed and still have 1/2 a gallon left. Once I get my Z running I'll put the truck in the garage and spray it as well so its one uniform color (previous owner spraypainted with cheap black paint).
