Engine Paint Help please

[jlemler]

So, my brand new engine, freshly rebuilt and painted has been put in.  I have been enjoying the heck out of it.  One day out of the blue my batter exploded.  The front of the engine on the drivers side suffered the majority of battery acid.  I thought I cleaned up well; however, it appears I have missed a few places and the paint has fallen off/come off.  I am someone upset.  I just have to clean it off better.

So what brush on product can I get that is brush on that matches my 1970 383 orange?  I want brush on I do not want to be spray bombing on the engine while it is in the bay.  The car is done.  I just feel cleaning and brush is the best way to go for control of application.

Any help, please.  Someone suggested Rust-oleum Omaha Orange is the color I want.  I just dont know if it will withstand the heat from the engine.
Thank you, Jeff

What paint did you use on it for the resto?

Someone on this forum shared this company with me and is what I used. I painted mine orange, I think the Hemi paint. But they have a few other colors. Of course the match may depend on the exact shade yours is.

To answer your question we need to know exactly what paint brand and type and color you used.
There are a million different shades between brands and types.

Don't know it was sent out for the rebuild.  I don't know who did the rebuild.  My father had it done and he has since passed.

Sorry for the loss of your father.

You can try one of the off the shelf engine spray paints (VHT, Duplicolor, Mopar) and dispense into a cup and brush on.
The other option is to either get it mixed locally or get from Roger Gibson / Frank Badalson (link in tparker's reply).

If you remove something with the color on it, you can have it matched at a automotive paint supplier.

Good advice, AND make up a loose slurry of water and baking soda and brush it all over any and all acid spots first and wash with clean water before you paint.

Actually you would want to sand or use a s/s wire brush to get to bare metal.
 Try a chemical acid neutraliser. Baking soda is a minimum cost and not a great, effective process to truly kill the acid.
 You should probably remove things like the exhaust manifold, Any accessories like p/s pump and brackets etc.. that are on the driver side of the engine since that is propbably where most of ther battery acid damage is.
Then you can spray the entire driver side and don't have to worry a lot about perfect paint match.

Preperation is always the most important factor when applying paint if you want it to look good and be durable.

When it comes to paint, you can spray or brush almost any paint.  The finish results will always look better if you spray.  But you can get okay results with a paint brush.  As for the paint, a 2 part paint will always be 10 times better than a single part (automotive paint w/ a catalyst vs rattle can) since it acts like concrete and has a chemical reaction that hardens the paint.  With engines that have a lot of chemicals and oils touching them it's wise to use a 2 part automotive paint to paint the engine.  Like others have said, you can have a local automotive paint supplier match any color.  The can put it in a rattle can that still has the 2 part catalyst too or you can mix and brush it.  Be aware, it's a lot more expensive to use good paint vs an over the counter rattle can.

My PPG guy really nailed it with the orange. He matched it to what appeared to be a fairly non faded part of a valve cover with original paint. I shot my entire NM 440 with it after stripping it to bare metal and shooting it with DP40. I couldn't be happier. If you want that formula, I'll gladly share it.

Very pretty.

I always use the Duplicolor engine enamel paint in aerosol cans and clear coat. Never any issue. Even used the wrinkle finish paint on my Hemi valve covers.
