I only recommend Dupont VARI-PRIME etchant, about $175 a gallon w/activator,.....it's the only thing that's going to actual "etch" it self in to the metal because of it's acid base, and actually form a chemical bond with the metal, the epoxies are just membranes that "sit" on the surface, to try and prevent oxidation to take place......I'd purchase 2 gallons and coat that car inside and out after stripping to bare metal, any bodywork (bondo) should be under the VARI-PRIME etchant,....2 parts polyester puttys/iceings on top of a 2K primer coat, on top of the etchant
If you choose the Dupont VARI-PRIME etchant,.....don't get talked into the "Nason" brand/line under DuPonts name, it's cheap crap substitute for DuPonts brand name VARI-PRIME,.....I'd then recommend coating with Duponts 2K primer surfacer ureahtane primer, finished with Dupont's line of Chroma Premier BC/CC

Especially since the lead has been removed from epoxy primers.

I haven't shot a car or worked in a shop, so take this as dummy input. I'd find a GOOD local paint store and ask questions. Mail order stuff is just as good, but you will want local experts to answer all the questions, and they deserve your business after answering all the questions! They will more likely have extra materials on hand in case of any issues. Find out what brand you want to use from bare metal through the top coat. If you mix brands, the finger pointing will start for any issues. Leave mixing brands for the experts. Once you have selected a brand system, find out what the time limits are and how to prep between coats. Figure out if you can meet these limits before you even start. Plan ahead! Even ask if there are guide coats to be avoided! Ask the store if you get a better deal buying it all at once, or not. See if there is a cash discount. Most pros have different guns for primer (it's abrasive) and color. Ask about that and cleaning supplies too. Be safe! Many modern paints, catalysts and solvents are very bad for you. Make sure you understand and prepare for the risks.

Thanks great advice.
Any preference out there on brand to use from start to finish?

If you have a dist. for Sikkens nearby, that's what I'd suggest, the best there is. Made by Akzo Nobel. web page

Everyone has their opinion and preference as to the best, I personaly don't care what the price is, I don't buy paint/products based on price,.. my preference is for quality mat'ls that last, maintain their brillance, color,....and a manufacturer that offers a start to finish program of paint componets,.....I've been painting/air brushing/pinstriping/ custom painting for 30+ years now,......I always find myself going back to Dupont BRAND name paint/mat'ls,......my only other recommendation would be Spies Hecker, a recent Dupont addition, or Sikkens,....that's it
IMHO I'd recommend Dupont VARI-PRIME on bare metal, covering your finished bondo work, no putties, 2 coats, followed by multiable blocked coats of Duponts 2K urehathane surfacer primer builder, any putty work, Evercoats 2 part Eurosoft, finial coat of 2K should be blocked to 600 minimum, Dupont Chroma Preimier Base Coat, with Chroma Preimier Clear Coat
IMHO, brands to avoid, Nason just pure crap, Sherwin Williams, PPG line, RM, OMNI more crap
