So I can tape off thing I don't want painted and block holes (distributor, fuel pump) then spray the entire thing with etching primer and paint over the primer?
Need I have any concern for gaskets, etc? | | | | | Joined: Jan 2009 Posts: 1,644 Shop Shark | | Shop Shark Joined: Jan 2009 Posts: 1,644 | You don't want any paint on gasket surfaces.If you're painting the engine you don't need etching primer.

I hear Dupli-color makes an engine primer for that purpose, but have never used it. | | | | | Joined: Jan 2011 Posts: 212 Shop Shark | | Shop Shark Joined: Jan 2011 Posts: 212 | Do it the proper, old fashioned way -
Get all surfaces super clean...clean with Acetone...
Heat with a Space Heater so the entire Engine is body temp or a little more..110 degrees is fine.
Use a good Grade Oil Base Industrial Enamel.
Add a little 'Pentrol' or similar to help keep a 'wet lap'.
'Mask' nothing, use a suitable good quality 1-1/2 inch wide Paint Brush...and, simply 'Paint' the Engine, one coat, no 'primer'.
Done right it will last forever, it is super easy to keep clean, Oil or Gasolene or other stains wash right off.
Bake for a week in the Hot Sun or with a Space Heater.
Done right, as described above...the result looks like 'Baked Enamel' and is gorgeous.

Pete Well I don't mean the surface of the gasket that, say, joins the water pump to the engine. I mean the edge of the gasket - whatever of the gasket is exposed between surfaces. Can this get paint on it? | | | | | Joined: Jan 2011 Posts: 212 Shop Shark | | Shop Shark Joined: Jan 2011 Posts: 212 | Things look neater if Gasket Edges are free of Paint.
Otherwise, it will not hurt anything if they are painted.

Pete | | | | | Joined: Jan 2011 Posts: 212 Shop Shark | | Shop Shark Joined: Jan 2011 Posts: 212 | Correct - Gaskets need to be applied to clean, bare Steel/Iron.

This ensures that the gasket mating surfaces have no paint and that the gasket edges do have paint. This also ensures that there will be no chipping of paint caused by lockwashers during the installation of the fasteners holding on the sheet metal parts etc. Its also hard to install painted fasteners without chipping them.
Paint on the edges of cork and thick fiber gaskets is good since it reduces oil seepage through the gasket material | | | | | Joined: Oct 2013 Posts: 367 Shop Shark | | Shop Shark Joined: Oct 2013 Posts: 367 | The original and therefore the proper way is to paint the engine in the assembled state.

I do believe the exact color is Ford Gray.  But I wanted some blue in the gray. | | | | | Joined: Apr 2014 Posts: 924 Shop Shark | | Shop Shark Joined: Apr 2014 Posts: 924 | Looks great! I hope to be picking out engine color/shade in a couple of weeks.
Thanks for putting up the picture. It helps to see it fresh on an engine as opposed to looking at a cap color.

Brad Yes it does and this is lighter than I thought it would be, but it's also wet. I'll get another shot of it dry tomorrow. | | |
