Laquer over rattle Can Primer?

I am very slowly preparing my Duster for paint, working one panel at a time. Rather than load up and clean my spray gun over and over with $$$$ worth of solvent, I'm thinking I can temporarily cover the bare spots with something like Rustoleum flat black primer. I am going to paint the car with lacquer (I and ten gallons of flat black that was given to me! - - the price is right.) My question, can I use the rattle can first, and then next summer spray the flat black lacquer over the thin-coat rattle can stuff??
Don't do it, solvent to clean a gun is cheap, like $15 a gallon for lacquer thinner or acetone at my local hardware store.
People always come up with the money and time to do a job twice, but have a hard time spending a few extra dollars to do it right the first time.
