This could cause an error message.

This way :
#local ldrawChromeFin=finish {
  brilliance 6
  diffuse 0.7
  metallic
  specular 0.80 roughness 1/120
  reflection {0.8 roughness 1/120 metallic}
}

The first metallic affect the specular or phong highlight. The metallic 
in the reflection block affect the reflection only.
There is NO specular block.
Reflection may be used without a block which is the legacy syntax. In 
that case, it will borrow the metallic of specular, but not the roughness.
