Engine Paint Methods

Some of you may have seen I recently suffered a valve train failure with my 351 Cleveland. The engine is now on a stand and the heads are at the machine shop. I'm trying to get ready to put the engine back into the car and I want to paint it nice and pretty before doing so. When I rebuilt the engine, I used Duplicolor engine paint in a rattle can. It looked really nice; for a while. Years later, it's a big mess. I have learned you just can't get durable, high quality paint in a rattle can.

Here are the engine painting methods I'm considering:

- Shade Tree Method: Buy rattle can engine paint at the local parts store. Mask and spray. See results above.

- Uncle Tony Method: Brush on a coat of Rustoleum Rusty Metal Primer and let dry overnight. Follow by brushing on a coat of Rustoleum enamel. Let dry overnight and brush on another coat. I find this method intriguing. It looks great and, apparently, the Rustoleum enamel is very durable and looks great for years. I also hear it's easy to clean. And Rustoleum paint is downright cheap. I'm not sure if this would work with my block and intake manifold since they already have old, rattle can paint on them.

- Paint Store Method: Ask local local paint store to mix up some Ford Dark Blue enamel and spray it on with a paint gun. I have spray equipment, but sheesh, my local PPG store wants hundreds of dollars for a quart of custom mix enamel.

- Eastwood Method: Eastwood sells engine enamel in a can at $35.00 a pint. Again, it requires spray equipment, but I hear it's good quality paint. Of course, I would have to order it and wait for shipping as well as pay for shipping.

Steve Dulcich Method: Spray on a light coat of engine primer from a rattle can. Follow with two light coats of VHT rattle can engine paint. Top with two coats of automotive clear coat. Dolcich says this method looks great and lasts a long time. When I first saw him demonstrate it, I thought, "Oh, that's nice if you have spray equipment and some good clear coat lying around. But then I remembered that I do have some very nice spray equipment and do have some SPI Universal Clear left over from painting my car. This would require a lot of careful masking, but maybe it's worth it. Hmmmm....

Thoughts?

secret to any good paint job
PREP
thoroughly clean engine of oil,grease,dirt
I start with a putty knife and take off as much thick nasty as I can
then move to heavy brush
at this point I prefer dollar store Oven cleaner , just buy a case it's only $6.00 a case
heavy coat of oven cleaner , let sit 5 minute
more oven cleaner , let sit
at this point even well ventilated fumes should be strong (cough ,cough)
wearing a mask , scrub time BBQ cleaning brush works great along with scotch brite pads (wear thick rubber gloves)
hose off and repeat if need be
when happy
I spray with acetone and wipe clean with paper towels
ready for paint
I have used oven cleaner on car parts, but never an engine block. I know it makes a mess of aluminum intakes.

Do yourself a big favor and buy some high temp paint from an automotive paint store and put it on with a spray gun. Motors out of the car anyway and it will hold up ten times as long
To repeat, paint store wants hundreds of dollars to mix Ford Blue.

Certainly a lot of products. Even Rustoleum, Krylon and Duplicolor have formula changes and a hundred products you never heard of cause no one store caries all brands, all products. Eastwood seems to have added a variety of products. Even Harbor Freight has boutique aerisols coatings.

I'd still experiment. Or brand mix.

Then again my 2014 Duplicolor job looks fine?

I think Klutch is enjoying his cars too much. Too much driving. Let em set on jackstands, the engine stays fresh. I only put 1000 miles on that Duplicolor paint job. Pretty sad. But one possible reason why I think I am good at painting.

The wall paint in my house is at least 20 years old. Excellent paint job. Or, no kids ever lived here. Nobody knows.
Yeah, maybe that's it. I put 7,000 miles on my Cleveland before I suffered a valve train failure and pulled it. I also drive it in the rain if it happens to start while I'm out. I don't care. I built the car to drive it and sprayed gallons of epoxy primer. Now the Cleveland is looking pretty scruffy.

Thanks for the suggestions, everyone. Right now I'm leaning in the Kelly direction. I already have some SPI Universal Clear. Somewhere. I better go find it and see if it's still liquid...

I should have kissed more girls. :ROFLMAO:
Well, yeah!

I have been painting engine parts with rattle can paint since the 1980s. I have used Duplicolor, VHT, and few others I have fortotten. In every case, it simply does not last. It gradually loses its gloss and then become very difficult to clean. I can't see how light coats are going to solve that.

And no, my kitchen oven is not big enough for a 351 Cleveland. :D
