when you go to get your house of kolor paint ask what kinda primers they have. they sell primers too. probably from pints to gallons then you will need activator too. really look for a primer that has a good bulid and fill that way it will level right when you spray it and you have a good primer fill on the car. You can use dupont primer on a car then paint it with house of colors. Spend your money tho and get some good primer from hok. dont go to pepboys and get can primer and paint your panels and expect it to come out like glasses usually that stuff just make the job worst the undercoating and prep work is the most important thing to making a paint job come out good. but im sure when you go look for your paint you can find a hok primer and activator.
