Here's a great rust texture that Xplo Aristotle posted a long time ago. It
renders pretty slowly but it looks realistic. The texture you're using now
looks fine to me, by the way...

#local Iron = texture {
   pigment {color rgb .25}
   normal {granite .3 scale .2}
   finish {roughness .01 specular .5 reflection .05 diffuse .8}

#local Rust = texture {

      granite
      color_map {
