Can anyone tell me what the tube dampers are made of? I am contemplating whether or not to paint them to match my bell (silver) or leave them natural. The decision comes down to how well the metal will wear over time and also if painting will have any negative impact on the effect of the damper. I'm guessing it won't do anything to worsen performance, but would like to be sure.

Are you referring to the heat shields?

I believe they are aluminum.   They do take paint pretty well, but the 6C45's run pretty hot, os be sure your paint can take the heat!

You can also find anodized shields online that look pretty swanky.

So are they for protection for the user from the heat or are they to sink the heat away from the tubes?

I'm using an engine enamel on the bell so heat won't be a problem - just deciding if I should paint or leave...

They provide a bit of noise shielding, and the spring pressing down on the tubes can suppress some microphonics.

Engine enamel is a very good idea.  You don't quite need the paint that is exhaust rated, but valve cover rated is a good thought.
