Paint question

I'm talking to a painter about my H. He is saying the engine should be painted 'high temp', but the only thing I've ever heard you gents talking about painting 'high temp' was the manifold.

So, regular paint on the engine block?
 
I think you'd really have to try pretty hard to get the engine block over 250 degrees or so.

And any properly applied paint should be fine for that.

Although it is certainly getting close to the upper end of what the paint can take, so the guy telling you to use high temp paint isn't necessarily wrong.

It's the safe answer for somebody who wants to avoid disatisfied customers looking for free re-work.

But, as I think you'll hear from many others here, even though you're close to the hight end of what the paint can take, it'll be just fine.

The exhaust manifold is obviously a different animal.
 
Yea,
Regular automotive paint will last just as long on the engine as the rest of the tractor.As long as the engine is prepped as well as the rest of the tractor(good clean metal with good primer.)

Just use high heat on the exaust/intake maifold and a good laccour or epoxy on the carburetor.
 
You should look for another painter. He is just trying to justify a high price.

Moreover, two different paints will never match and certainly will age to a different color.

Heck, the surface temps of a dark color car can probably reach the engine temp of 180 degrees under perfect conditions. And the engine doesn't even get much ultra-violet exposure which is tuff on cheap paint.

Why can't you take the tractor to the USN base hobby shop? Don't they have a paint booth? Then again, maybe it is a liability issue with govt.

They shut it down. Insurance and environmental issues.

I should have been more specific. The painter is one of the aircraft airframe mechanics in my squadron. He has painted jets and cars for years, and is willing to pitch in to help paint my tractor with me. We're talking about materials and such. I told him I didn't think the engine got hot enough, but he's thinking automotive engine, so there is probably a difference. So, he'll be happy to know the answer from here.

I was going to go with an out of the can silver for the manifold, but the more I think about it, the more I want to go with red. The heat shield is going to need high temp as well. Where I'm going to find a high temp red to match the DuPont paint we're going to use, I don't know.
 
I use the Black Rustoleum "High Heat" for grills paint for my manifolds. They stay black and do not rust.
PS: I thought you Navy guys painted everything gray! LOL and thanks for serving.
 
He doesent know mych about tractors and engine heat. Never seen hi-temp used If you want it original use the same paint the manifold will burn off where it gets hot and the rest will stay ok. Just ask question next time you go to a show. You wont find any hi-temp paint used. Every thing was red.
 
Mike,

I paint my manifolds with a flat or glossy black high temp paint. That way I don't have issues trying to match colors of different kinds of paint.

My thoughts exactly. Find a different painter.
 

I use the Cast Blast hi temp. Formulated to look like bare cast iron. Photo is toolight, it's not thet silver really.

I"M partial to keeping it red, Gordo, but that corvette silver stuff you mentioned is my backup.
