Firewall Primer?

[JayEstes 172]

I'm at the point of being ready to go back with paint in the engine compartment on the firewall. I've got it nice and stripped down. Was about to prime it, and I wondered... I've got the 500deg engine enamel for the paint, but what about the primer? I don't know if it can take the same heat, and I REALLY don't want to have the primer melt off under good paint.

 

I don't really even know if that could happen, but thought I would ask.

 

Perhaps using the enamel right on the stripped firewall without primer is a good approach? Anyone have any opinions/experience on this?

 

Thx in advance, Jay

I went down to the bare metal and then used a marine epoxy primer. I wasn't that worried about heat as I was about rust. In fact, I used this epoxy primer on the entire car. I painted the underside of the new floor pan with it, then paint, then undercoated it.

 

 

 

and then a flat black

Thanks for the inspiration. Mine won't look as good but I'm going to try my best with the engine in the car. I'll remove all the wiring harnesses I can and the solenoid and voltage regulator from the wall.

 

I already removed the Battery tray.

For the engine compartment and firewall I would an automotive exterior paint and primer/sealer such as epoxy like BigDuke6 suggested. There are also acrylic enamels, or single or two stage urethanes. I would not us an engine enamel on the firewall. Dpending where you live, laquer paints are also available but they may not be as durable and last as long.
