Thanks! Very Good! But...
Update rc3metal.inc:

#macro RC3Metal_Galvanized_t (c_Dull, c_Shiny, Dull, Shiny, Dark, Light, Shine,
Turb, Scale)
  #if (RC3M_Debug) #debug "RC3Metal_Galvanized_t()...\n" #end
  { crackle solid texture_map
    { [0 RC3Metal (c_Shiny, Shiny, Light)]
      [Shine RC3Metal (c_Dull, Dull, Light)]
      [1 RC3Metal (c_Dull, Dull, Dark)]
    turbulence Turb
    scale Scale

Scaling crackle is required surely!  :)
