This is probably the most important part of installing a mini-spool, or doing any service to the rear differential of a truck. What color should I paint the cover? It's a GM 8.5" 10-bolt, if that matters. Red is the obvious choice because it's one of the fastest colours. I'm open to suggestions, however.

The amount of heat it would radiate wouldn't be substantial.
 
Ultimately, satisfaction depends on quality and formulation of your materials.
A good BBQ paint vs. cheap automotive paint?
Abrasion resistance is needed. Frame paint??
 
Some country song has a verse that goes: red- red- red- red- redneck......

Yeah I painted diff covers years ago too, guilty. If this is under your '88 and you spooled it then it should be painted red.

And you've got the battle flag rear window shade thing hopefully.

Exactly, most of the heat loss from a diff is convection.

A better black body would also absorb more heat from a hot road surface (again, negligible).

But what's REALLY funny is that white out (correction paint) is almost a black body in the wavelengths that transmit heat, but a really good reflector of visible light.

Cover paint will be the LEAST of your worries running a mini-spool.

Oh. Should I paint the entire axle housing?
