Reply to "Engine bay paint options...?"

I doing the same project. Forget Rustoleum, its crap if you use their red oxide primer which never seems to harden and they the top coat ends up peeling off with almost any pressure from your fingernail.

I'm looking into either linear polyurethane (any color you want) or a two part paint acrylic enamel that you add hardner to. I noticed Summit Racing sells some of these paints. It use to be that you could buy automative paint like Centari or Enron. Supposedly Pettit and Interlux do make paints that are more user friendly.
They offer enamels, one part polyurethane products (No catalyst, "urethane enhanced enamels"), and two part polyurethane's. Hard, harder and hardest (Enron is a two par urethane).
Each of these companies and others also offer professional lines of products. Enron is a professional product.

I live in California which has the EPA protecting even the hobbyist from destroying the planet. I spoke to a paint supply house a few weeks ago...he told me that depending on what I tell him I'm going to apply the paint to, will determine what he can sell me. If I tell him I'm going to put the paint on a gate, he can sell me X, if I tell him I'm going to spray my car with it he can sell me Y. So basically I have to call him four or five times and say I'm putting on a lawn mower, a fence, a washing machine, a boat, and commercial boat. It's nuts, he told me there are products that are incredibly durable that he can't sell me because I have to have a special filtered spray booth...or I have to be a marine application, or it has to be applied only on Sunday. etc. I love government.

I leaning to acrylic enamels that you add a hardner to and they are very very durable, you can drop wrenches and they resist chipping, there also flex additives that you add to the paint that allow you to paint plastic bumpers which allow flex without chipping or cracking. Take a look at this link:
