Duplicolor ceramic engine paint issues
I always put down a coat of Gray Automotive Primer Surfacer to seal up the cast iron surfaces, then when you spray on the ceramic aerosol high temp engine paint it does not shink down into the rough cast parts surface.
The primer surfacer stands up to the engine temperatures and does not peal off.
Provides a good base for smooth steel parts like valve covers too.
I paint valve covers, intake manifolds, and transmissions all silver. They all get a basecoat of primer surfacer, then Chrysler 2003 minivan silver basecoat, then automotive clearcoat to make it shine and chemical resistant as the final finish.
Here is one, primer surfacer all parts, then high temp ceramic on the engine block and heads, then basecoat/clearcoat on the valve covers and intake manifold. Holds up to heat well and has a decent final finish.
Primer surfacer, then base, then clear.
Primer Surfacer, then single stage black acrylic enamel with the hardener.
Primer Surfacer then Base/Clear
