What Primer To Use?

[SpeedThrills]

I haven't done body work for about 23 years. I'm starting on my 74 Dart Sport, that I'm cloning to a 70-71 Duster.
The primer I used in the past was porous, and of course would allow rust to form.
What should I use as I strip the body and do various bond repairs and weld patches?
I plan on stripping the car w/ a sander as I go.
I'm going to spray the color in the jambs (doors off), trunk and engine compartment, too, if that matters any. I'd love to spray the body too. But space is a big problem there.

PPG DP-80 epoxy primer is what I use, can be the 90 (black) also. you can not go wrong

Epoxy Primer (2 part ) would be my choice available in black, grey or white depending on your top-coat color

Don't use any 1k (non catalyzed) primer.

DP-80

PPG DP90LF or SPI epoxy primer in your choice of color. I've used both with good results, but currently prefer the SPI because it's a tad cheaper and the UPS dude drops it off instead of me going to the paint store.
