Tony,

In the early 60's I went to the Palm Springs Road Races, and stopped by 
a Concours. There was a very pretty Jag XK 120, like I had owned, with 
the hood up.  A great deal of time and effort went into making the 
engine compartment like a jewel box.

He had even stripped the black paint off the radiator, and polished the 
tanks.  I was beautiful.

However, there is a reason that manufacturers use a black finish on hot 
surfaces.  That is "thermal radiative emissivity".  The Jag was designed 
for the cool weather of England, in those days, and had a bad habit of 
overheating in our climate.  That's why the Jag owner complained of 
overheating.

It is pretty, but not helpful.

A magnet tells me my expansion tank is brass, and the straps are steel.

Steve
