My understanding is that a black surface radiates heat best and absorbs it best. A shiny surface would reflect best and radiate less
But that is probably only a theoretical issue here unless you plan to race the car.
I got my ZF looking nice just with steel wool-- start with more coarse to get the grunge and larger texture off then use fine to get a shiny surface.
To get a mirror finish you will need polishing wheels and small cotton tools to put on a Dremel or similar device to get all the concave areas. It wasn't worth it to me and I didn't really want a near-chrome look anyway.
The surface crack looking things come off with steel wool.

For what it's worth, my ZF was media blasted and clear coated by the previous
wner of my car. You can see pictures on the registry (VIN 5186). I've had my
ar serviced multiple time by Cory Gehling at Collectors Choice in WI and he
old me a long time ago that he was told by the ZF people during one of his
raining classes that the case depends on the natural porosity of the aluminum
o dissipate heat and that the case should not be painted or polished. That
aid, I haven't had any problems with mine for the 23 years I've driven it and,
ccording to Mike Drew (who drove my car at the Road America vintage races this
ummer), my transaxle shifts very smoothly from other cars he's driven.

don't know if this is true, but I heard that a polished ZF won't dissipate
eat as effectively as the stock finish.

Hello Friends ,
I would like to begin polishing my ZF Transaxle since it is currently out
of the car .The ZF is 37 years old.The outer Casing has what looks like
stress marks or scratches on top.
Does anyone have any hints on how to polish to a mirror finish ? I really
do not want to take the whole unit apart.
What tools are needed?
What sandpaper to start with ? Emory paper ? Wet Sand ?
What air tool is best to use ?
