Painting heads and jugs

[bigd1960]

Took my engine apart and thinking about getting jugs and heads painted. My local powder coating shop tells me they can do it but I'm afraid that it will retain too much heat. What other solutions do I have?

I am sure someone else will chime in shortly... but, If I am not mistaken, black powder coating does the reverse... it does get rid of heat!

I don't think paint is going to hold up to good, but to each is own.
I had mine Powder coated several years ago and have not had any problems with the bike heating up. I had the powder coating shop send them to "Diamond Cut" and had them do the show diamond cut. They look good to me :2thumbs:

Thanks. Was just worried about the possible heat factor with powder coating. Maybe I think too much!
Have a good one!

When I got my bike, the last guy had painted the jugs, and they were looking like crap, So I repainted them last year when I painted the bike, and once again there looking like crap. And I used some high $ paint. If you powder coat them and then have them diamond cut, I think that would cool as hell.

POWDERCOAT , DIAMOND CUT = NO PROBLEM

 

[bigd1960]

And those who know me would agree that
No Problem is a good thing for me

Dont paint...Powdercoat only.

A buddy of mine had his powdercoated and then diamon cut..its been over 5 years
and they look great.

Paint would look like crap in a year

just my .2

Painted mine a while back with ceramic header paint, lasted ok but it was a temp. Mine will be back from powder and machining next week!:2thumbs:

Thanks
Appreciate the feed back. Turned out a good polishing compound and hours of elbow grease worked wonders.

Ceramicoat will last longer than powdercoat. Under higher heat powdercoat will grey.....like 400 degrees. The heat shields on my twin cam turned grey from glossy black. They also softened to where they started getting tool marks.

Eventually you will have to polish glossy powdercoat. Less so with Ceramicoat.

I did my latest exhaust with jethot Ceramicoat and they are perfect. Not cheap, but perfect.

Well, as far as I know ceramic coating is often used to prevent gasses cooling in exhaust systems, or keeping the heat out, say in space shuttle. i.e. its great insulator.
A 5 mil steel sheet with a 5 mil calcium silicate coating has about 1/90th the thermal conductivity of a plain 5 mil steel sheet.
So if you are worried about jugs ever overheating I would not ceramicoat them, though the coat is really thin, but still…

True, but I think HD's black is a form of Ceramicoat.

Yeah, in these thicknesses (?) the difference in cooling is most likely theoretical... Coating may (again in theory) spread the heat more evenly... Not bad.

although the coatings look nice... I personally would not coat my jugs/ heads...

If I ever take mine apart I will get the S&S 124 kit and discuss color options with them. They sell black and warranty them so I am sure there are some options....even if it is black.

Then diamond cut them like my TC 124.
