Polyester Primers

Thanks for all the input,guys.Well,I dont know if I want to use the polyester.I want a primer I can wet sand and then pressure wash the hell out of car afterwards,makes it much cleaner.I found a gallon of etch from a previous project I can use,so I may just use that and get me a good 2k primer.I found a site called Tamco that has a gallon of 2K primer plus activator online for $69.95 with free shipping,looks like a great deal.
