Engine compartment Paint

[bigge31566]

Im going to paint my engine compartment, trying to decide to use acrylic anamel or acrylic urethane. Someone told me enamel was more heat resistant. I was going to use Por 15 but cant figure the bondo issue when to put it on to work it. Which should I use

Long time ago, I just used a DuPont enamel and a hardener and that was very durable.  I'm sure the urethane is more durable.  Even the rattlecan finishes are acceptable.  Others on here will also provide their experiences and successes.
