My 71 Duster Project

Well, the teardown process is still going well. I was actually able to bust some rust and lay some piss can primer on it. Speaking of which, I have some questions in regards to ordering paint, primer, etc...I have looked at alot of the websites you guys recommend on here and the process seems confusing. There are too many types of paint. I am looking to shoot single stage acrylic enamel vice the base clear. I plan to shoot the gun primer as well, vice the piss can, but are certain primers compatible with certain paints? Looking at how much body work I am facing, I would like to use a high-build primer to even out the little imperfections. Any thoughts? I wish that I could just order a kit that has everything! Here are some progress pics.
