Green engine paint to prime or not?

[RickMcK]

I am getting ready to paint my new block, pan, and heads. All parts are bare clean metal. I will apply metal prep prior to painting (phosphoric acid). My question is: Should I use primer when using Hi temp green spray enamel (like what Mac's sells)?

What does it say on the can? Remember that the pan is black.

IMHO There are better paints than the high temp spray paint if your interested.

Rick,
I've had fairly good results with MAC's spray can green engine paint. I
learned early on to spray an even coat of Rustolem gray primer on the parts
prior to the green. Doing this reduces the number of coats required and gives
depth.

Thanks. The can does not say anything about priming.

WOW I did not know the pan is to be painted black. THANKS

What other brand of paint is better than the spray can stuff from Mac's? I have had good luck with it on the intake manifold when followed "VHT" by high temp clear coat.

This is what I use.

I agree with the Bill Hirsch paint. I am ordering 3 quarts this week.

Bill Hirsch paint is the very best there is. It can be sprayed or brushed on clean bare metal. Flows out nice and smooth and is durable and very long lasting. Very resistant to gasolene too. Has a long shelf life. I think it's about $35 a quart. A quart is more than enough to paint an engine.

The stuff Roy Nacewicz is the best match to the authentic green Ford used.

Painted my block and it hardly put a dent in a Quart, so yep goes a long way. Mine is brushed, really flows on great.

I like brush on better than spray. The brush marks do not show because of the roughness of the cast iron.

Imho. I suspect that the paint on the engine was for show room appearance only. Nobody at Ford expected it to survive for very long. Doing anything more than blowing alkyd enamel on a clean metal surface is more than what was done at the factory.

But, then, we are not 1930,40 customers, are we?

Where do you get the Bill Hirsch paint?

I used the engine paint from POR 15...Brushed it on and it smoothed out well..

The pan is black only on early 49 cars and back. 49 and later pan is engine color.
