Properly painting the short block

-
What about these three? I'm not really an automotive paint expert by any stretch. Can I use the epoxy primer with the urethane topcoat? I'm thinking about gray for the block. I had black but it was a mistake to be honest. Makes it really tough to find oil leaks etc. View attachment 1715864600

Sorry to pester. Would these be considered catalyst paint? And would the epoxy be compatible with the urethane?
 
Don’t paint where the gaskets sit. Then when you pull the gaskets it won’t pick up the paint. I usually use the gaskets as a template to tape off a short block for paint.

All aluminum parts should have a light coat of self etch primer. The iron block scuff all machined surfaces to be painted with a coarse scuff pad. Wash all iron surfaces with thinner but avoid self etched primed parts. Then prime the whole thing with engine primer right over the self etch primed parts. Then Paint it what ever color you want withing 1/2 hr.
The above tips are great for Prep. I have had excellent results with Eastwood's 2 part engine paint. Being catalyzed, the paint hardens. I painted the engine in my Cuda 8 years ago, and it still looks good. Plus, it is reasonably priced.
 
Never heard of this can you provide a link?
Sorry it took so long, it was buried in the corner. I apply 2 coats of this, letting each coat dry about 15 minutes. Then I trim the parts that need paint with an X-Acto knife. It's similar to rubber cement. After you trim off the excess, it lifts off easily. Then I paint everything in the area. After it dries, peel of the mask with the paint on it. It easily lifts off. RC modelers have been using this stuff for years. Give you a sharp, crisp line every time.View attachment 1715866253

Yes, all will work together nicely. You'll just want to be sure and follow the p sheet for th epoxy and the urethane.

Should hold up nicely.

painted one last night. Used VHT high heat enamel with ceramic. Both primer and paint. Scuffed with 300 grit prior to prime. Came out nice.
 
Hold the timing cover up against the block, use a sharpie to mark out its outline. Tape everything off inside that outline and the head deck surface along with the bottom side of the block. Use high heat engine paint of your brand choice. 2 light sprays, let set 10 minutes between each spray then 1 heavy wet spray (spray clear coat on immediately after you spray wet coat so it mixes with paint otherwise clearcoat will peel the color paint up out of the metal pores) let dry overnight and voila! There ya have a perfect paint coat. (All this was based off of instructions I received from high dollar painters at my autobody assembly job) This is my 318 magnum dirt track engine I just painted the other night. Paint job is tough as nails.

also clean VERY thoroughly with carb cleaner! AND PRIMER IS NOT NEEDED. :thumbsup:
 
2 posts up (#35) - don't paint the flat machined surface where the distributor goes. beyond the distributor and paint chips it makes it hard to seal the oil seal at the back of the intake manifold. I have found that a last wipe down with BrakeKleen is the key to adhesion. It gets the last oily residue out and dries without a residue
 
The flat out best paint jobs I have ever seen on an engine were done with standard automotive car paint.
