Heater Pipe Rusting..Painting? (dd)

[Arnold]

Heater pipe rusting on one of my d/d. There is a surprise
This ain't gonna be fun to change :evil: One day it will have to be done.
Just trying to postpone the inevitable a bit..

  I am guessing either Hi heat Tremclad Rust Paint..or some sort of hi temp epoxy or something else that will stick to rusty metal and tolerate hi heat.

  Any ideas please

  Thanks
