Painting engines

Have a pair of orignal Cummins 504's with many hours and much rust...particuarly the manifolds.
Anyone have any experience with painting old rusty marine engines. Looking for recomendations. Should I prime them? Are there special primers that take the heat? Recomendations on paint? Found that Duplicolor makes a match for the Cummins beige paint. Is this stuff any good?

Giff,
I have the same engines. I stay on top of mine year to year by touching them up where needed. The outsides under the mainfolds are the hardest places to spray. I clean them down with acetone, wire brush. Used to prime but gave up on it a few years ago. I found that spray appliance paint works best, the color is a great match and it drys hard.
This is just touch up if I had them out would probably do it differently.
Not sure if all would agree but my 504's look pretty good for their age.

one done in the shop...the other done in the boat........just a matter of time and determination.....dremel with wire brush works great on hard to reach spots........the shop refinish i unbolted everything and sand blasted....but from 10 feet away they look the same
