It is best to stick with a single paint "system" but the ppg epoxy is about as good as it gets for epoxy primer. You should be fine using another primer/sealer on top of it.

In my rookie opinnion the bare metal treatment you apply is probably the most important step.

Good luck and post some progress pictures.

Edit: be sure to wear a respirator and mix it exactly as the can says. That DP is some strong stuff.

that's what I thought. The ppg epoxie runs about 115 buckazoids per quart so I intend on using it up. progress pics can be seen in my bodywork thread on this site.

Evercoat makes a really nice epoxy primer surfacer for about $100 per gallon with catalyst.

Any epoxy primer will be very chemically forgiving. You should be getting 100% mechanical adhesion with another undercoat like sealer or basecoat when it comes to an epoxy primer with zero chemical adhesion. Epoxy primer locks up solid. I've screwed up basecoat and sealer before on some bicycle parts and even a few guitar bodies and took them back down to the epoxy primer with paper towels and laquer thinner. It pulled the basecoat out of the 600 grit sanding scratches without touching the stuff.

You should be fine with the PPG epoxy primer under Nason sealer, base and clear as long as it is sanded and cleaned fully. Nason's sealer doesn't mix with a reducer or catalyst. I think it's about $40-50 per gallon.
