Was beginning process of painting block. I bought some Plastikote engine paint. I was surprised not to see any mention of a primer. Anyone know if there is a primer out there? Can I spray the paint direct on the bare (and clean) metal?

The block is just back from machinist, and is bare metal. I was going to degrease with dilluted simple green.

Thanks

You don't need primer on the cast iron parts. The tin should be primed with a good self-etching primer. Joe

I didn't use primer on my new rebuild because I'm going for NCRS standards. However I did use a good enamel reducer to clean all the parts before painting. I don't suggest using simple green or any other similar cleaner. Anything that doesn't get rinsed off completely could cause the paint to fish-eye, bubble, or just not adhere properly. I bought the enamel reducer at the local aoutbody/paint supply store. They gave me the suggestion and it worked great.

I didn't use primer on any of the tin either because of NCRS standards. All my paint turned out great except for one valve cover that I forgot to clean with the reducer. I removed the paint and cleaned it with reducer before repainting it. It turned out great afterwards.

Good luck.

Wipe it all down with lacquer thinner or reducer first. You shouldn't need primer.

Thanks for the replys.
I ended up spraying it with simple green diluted with water and scrubbing it with a 3M steel wool substitute. Then I sponged the surface with plain water until the surface rinsed clean with no suds. After it dried, I wiped it with acetone. Then I painted. The scouring pad and simple green really did a good job getting rid of the very slight surface rust and any remaining oils/machinist fluid. Got the first coat on now...
