2G primer bay question

[DSM_GSX01]

I want to know what primer i should use on my engine bay. The bay is down to bare metal in areas and has just little paint left on it. I was told use epoxy but have no clue. Im new to painting. Any help on what to primer with will be great. Im going to do base coat/clear coat.

If you want it to last a long time i would just shoot it with a single stage urethane. No need to base clear in the engine bay.
