So when I walk around the pits and check out other peoples cars, one thing that impress' me the most is a clean engine bay, well put together and thought out. No after thoughts, or sloppy hoses.
In the center of this is a nice shiny orange hunk of steel...

What have you guys found to be the best way to do this for appearance and durability.

Is it a primer, or particular paint. With a fresh block from a machine shop, do you wipe it down with thinner or acetone???

I know the veterans will have the answer

Thanks

1) Jet wash and dry

2) Lacquer thinner and dry

3) DP type primer

4) Single stage Urethane..will look and last new forever with an easy to clean gloss.

I like to paint everything individually, block, heads, oil pan, front cover, valve covers, water pump housing. It takes more time to mask everything off, but I like the look with bright fasteners. This is a race car, not for show.

I agree and typically do the same. I like to paint the blocks so when I am working on them dduring the build, it is much easier to clean ( which often times is 2 or 3 times)and you dont have to worry about flash rusting so much. I almost do everything in Urethane, so I'll prep the pieces then just paint them when the block is getting painted as well. I too like the looks of fresh fasteners. It takes a lot of time to do it this way, but the results are always excellent and my customers have come to know me for clean, nice looking engines as well.

my block & heads are 2 pot baked enamel. was trying to hide the fact they were aluminium but the silver is obvious in places the painter masked off. mine is 4 seasons old & still looks like new.

So does this mean I need a spray gone and or a very large oven...
I assume the urethane is a spray gun only application

The baked enamel it is in fact baked?

being an alloy block it was media blasted first, then put in a powerwash machine, then masked, heated & then sprayed like a car, then baked for 4 hours. it's a very hard surface. my local ceramic coating applicator did it for me for 2 trays of beer. it was a trial on a new product & we were both impressed with the result,

Got ya. I picked up my short block completly assembled and would rather not take it back apart.

I think I can mask it off and spray it with urethane...I hope

honestly i get lots af spectators in the pit wanting to touch my block & heads, it looks sooo smooth & shiney. i don't think you'll have any probs painting the complete assy. just remember to run around with a razor blade on all your joints before it sets real hard. this will make it come apart easier without ruining your finish.

I never would have thought about running a razor blade around the joints, good info.

I usually paint mine apart as I like the clean line look of the gaskets etc. However it would be easier to just spray the whole thing.

Let me terrify you all by saying the best engine paint I have found is Tremclad paint in a can, applied by a brush.
It turns out smooth with no brush marks, takes tremendous amounts of heat before discoloring, and stays shiny, clean, and does not fade or peel.
Easy to touch up too.

I usually paint my motors after there assembled, mask as needed and buy several cans of Mopar engine paint or your favorite brand and color and I do make sure that all the oil is rinse off with a good brand of petroleum based cleaning solvent and then a quick rinse with laquer thinner and then use a face mask or resperator as some of the paints are not good for your lungs Be careful of sparks also

Too bad it's difficult to recreate the factory sheen with it's thin coat semigloss look..any suggestions there?

i clean everthing with brake parts cleaner. then mask everything indavidually, prime with plasticote engine primer, then at least 3 coats of what ever color engine enamel, then a couple coats of plasticoat clear engine enamel. all the motors i've done like this turn out really nice!! the clear keeps them looking wet.

I should probably start a new thread instead of hi-jacking this one but since it concerns the painting of engines I'm going to ask...

How many people have powder coated their blocks, heads, intakes etc... instead of paint? I've painted my engine with single stage urethane numerous times and yes it looks really nice for the first year or two. That being said though after splashing some hot antifreeze on the paint it discolors and I've had a couple small spots peel where the a component wasn't obviously clean enough. I know paint can be touched up and I'm being anal here but it would seem like the powder coat option would give better longevity- or are there pitfalls?(other than cost)

I had a aluminum intake and a set of cast aluminum rocker covers powder coated once back in the ealry 1990s, never again That darn powder coating is a great insulator, but it KEEPS the heat in instead of keeping the heat out. Heat rises so when it is hot in the motor and aluminum coducts heat very well and then the powder coating keeps the aluminum sealed up the parts get so hot you can't harddly touch them

OK, I'll ask an obvious question - how close is the Tremclad color to factory? I've seen some well intentioned companies that use the factory name but aren't even close. Is there a company that produces a dead-on product?
