How hot does a doff get?

[Cornishman]

How hot does a diff get on a road car? This car is driven like i own it,not stole it, so I assume not very hot.
My question is based upon the type of paint to use, ordinary spray can black, Hammerite smooth or VHT SPRAY. Any suggestions? I am not up for powder coat etc, that will take too long, take funds from other parts of the car and mean it can't be a concourse winner!
Thanks

The only person I can think of that may have a differential temperature sensor routed to the instruments is DQ.

Yes DQ and the guys with the real Alpinas. Several Alpinas had diff oil temp gauges. Admittedly only in the 80s/90s.

But several diffs have cooling fins so 100deg cels would not surprise me.

Engine block paint would probably be a good compromise. Easy to apply, and engine block will probably get hotter than the diff but not as hot as an exhaust, is good for iron castings and in oily surroundings.
Cheap as well.

Hammerite is fine on brake calipers so I'm sure it's fine on the diff.

It turned out too Grey

Thanks, but I had already painted in in VHT. OK, but too grey for my me.
So I will see how well it holds up against use.

Ok, that was a bit grey
As "Polariscsl" above mentioned that Hammerite works fine on these areas.
I could definitely confirmed above after years of driving with Hammerite on callipers and diff.

VHT has a flameproof line of paints
in my case i use a 750 deg. celsius rated black from rust oleum, i have used in my exhaust manifolds three years ago, and the paint is still there

@arde, thanks for giving me new ideas :wink:
