I'm at the stage in my project that I'm finishing up some body work and getting ready for paint: just ordered some single stage paint at NAPA in Toyota 854!

But, I'm unsure where to go with primer, and am a bit confused by the options. Not sure which approach is best for my truck. (I have read through "Painting / Finishing 101" by @copasspupil.)

The amby doors, sides, aprons, and fenders have all been sanded down or sand blasted. I used Eastwood's Fast Etch on any bare metal, followed the directions, and then applied two thin and one medium coat of Duplicolor Filler primer. I started with the Duplicolor primer due to the convenience of the spray cans, and got a good price on a bunch of cans. This allowed my dad and I to chip away at one panel at a time without having to mix a batch of epoxy primer.

The paint guy at NAPA was really helpful, and was encouraging me to use epoxy primer before painting. The TDS sheet for the Crossfire brand paint I bought stipulates I use a Crossfire primer before spraying color (I'm sure most brands suggest the same.)

I'm not sure where to go from here given where I'm at in the project.

• Can I spray an epoxy primer over the Dupicolor filler primer I've used? That, in my mind, would be the ideal solution since I have so many panels already primed with that product.
• Is there a different approach I could use with the Duplicolor primer, like applying a sealer to everything, then spraying some two part primer?
• Other suggestions or things I'm missing entirely?

Our plan is to the tub / body and the fenders and front-end panels done first so I can drive the truck a bit this summer, and then work shoot color on the remaining panels, and reassemble all when done. I've already repaired and repainted the hard top.

I appreciate any help!
