I once melted the soles right off a pair of work boots!  AND burned the soles of my feet.

 

Worked on a roof one day and has to go get something out of the truck and my boots started sticking to the tile inside the building and leaving imprints.

I painted my Briggs Twin tins with Rustoleum High Black, inside and out.

I did not bother with painting the engine.

You guys are out of my league…

Don't feel bad @Horse Newbie , never painted an engine. But almost every other part on these WH tractors.

No worries. You can soon.

Joe, do you find any discoloration of the paint right near the exhaust outlet on a working tractor?

I knew I forgot to look at something......tomorrow if I can remember. lol

 

Now for more, I know they ceramic coat headers and it has a lot to do with heat. They want it to stay in or transfer out?

Came up with this on Google WOW WOW WOW TMI

• Improves thermal efficiency of the engine system.
• Reduces radiated heat levels on all exhaust components, especially effective on tubular performance headers and exhaust manifolds.
• Maintains uniform temperature throughout the exhaust system.
• “Trapped” heat improves exhaust gas velocity, effectively “scavenging” each cylinder and increasing horsepower and torque.
• Keeps the engine compartment cooler.
• Extends header life.
• Lower temperatures extend the life of neighbouring components.
• Improves thermal oxidation protection at higher temperatures.
• Reduces parasitic drag losses.
• Provides a custom appearance with flat, satin, finishes.
• Easy to clean and maintain.
• Ceramic coating provides protection against rust and corrosion.

I don’t feel bad… maybe lazy…

Just much respect for people who do that type of (lotta work) work !

They could have just said “looks cool”, and that would sell me !

Although this is true I think keeping in mind where this applies is important.

Ceramic coating usually is done on cars, especially high horsepower cars. With high performance vehicles keeping the temperature in the egine-bay as low as possible is important to keep things from burning up or exploding.

Also if you run a turbo-setup it's important to get exhaust gasses to the turbo as hot as possible. That's because hot gasses contain more energy to spin the turbo, thus creating more boost and/or being more efficient at creating boost.

So that's why it's key to keep heat in the exhaust and out of the engine-bay. For that same reason you sometimes see that they wrap the headers and downpipe of an exhaust system with heat resistant cloth (fiberglass?).

 

Long story short, not sure if it ceramic coating a lawntractors' exhaust will boost the performance. 

That being said, it does look pretty friggin' cool

I just recently got a price quote from Jet-Hot coatings. 

To do their service in the (closest to chrome they have) is over $300 for a Kohler twin muffler. 

That said, keep in mind the mufflers alone are getting pricey too and actual chrome mufflers are rare as hen's teeth. 

That coating on a solid stock original Wheelhorse muffler would last forever, and not rust or discolor.

You and I would get along @Cee245 I painted a screen on a 416 like that once and really like the way it pops. Some day when I got nothin better to do the 520s are gonna get it too! 

 

Likely!  I didn't have much to do, so i painted it.  What is weird is i can barely see it! This picture doesnt do it justice.

 

I was cleaning it up after replacing the module under the flywheel and thought what the hay, ill spruce it up a bit. 

 

Also, i greased the gear on the bottom of the  steering shaft finally. I had forgot that you have to turn the wheel to get to that grease fitting.  It's been over a year since ive done it. @peter lenais gonna kill me! Lol

I have read that black engine paint transfers heat better than other colors.

My mother always told me that if I am not in the sun, black clothes are cooler because they transfer heat away from your body, but in the sun, white is cooler because it reflects the sun. I never successfully argued with my mother.

That’s good!  Your mother was correct.

@Cee245   nope not going to kill you , glad you got to it  !  might do that red screen on mine  too, looks sharp , pete

A little discolored under exhaust pipe. I think it is more black soot though. ??

That looks fine to me.  

 

 

On our engines we paint the WHOLE block. 

On the fins 2 light coats. Barely even enough to cover.  

 

The heads we leave bare aluminum for best heat transfer.  

 

The are where I see discoloration is only immediately at the exhaust pipe outlet connection. The rest is perfectly fine.

From the great quote of Stev a saurus "Let not over think this thing"!

But either way I think we are okay.
