Painting Exhaust pipes and under carriage ?

[greedy geezer]

I'm doing a clean up and painting my under carriage with Rustolium Rusty metal primer it's coming along and I should be done soon , I have this High temp silver from a boiler job left over I know it won't make the pipes look chrome, but have use this paint on some very hot metal and it gives a real nice aluminium finish, I'll also do color over the rusty metal primer maybe some of the appendages under the hood power why not ?
