12 Bolt Rear - Black Powder Coat Finish or Black Paint?

Hello guys,

Looking for some guidance. I have a 12-bolt rear with the axles and bearings out. I want to give it a good finish before re-installing the new bearings and axles and installing in the car. The ring and pinion and the posi unit are still in. I plan on rag backing the ends and then sand blast all the grime and old paint off.

After that I want to paint it or powder coat it. I have local guys that can do either. My question is that if I powder coat (which requires a heat treatment to melt the power app) do I risk damaging and components in the housing? The powder coating is a better finish but if the heat will raise any issue then I will go for the paint.

Any thought on this? Thanks.

If the axles are out, I rag pack the ends and the 12 bolt cover is on can they blast and powder coat it without doing any damage from the heat to the ring, pinion and posi?

Any help would be appreciated.

Thanks

It wont hurt anything. Go read your other post also. I had my top bows powdered, and theres plastic washers in it.

i work for a powder coating manufacturer,and we sneek our small parts in the back door...never did a rear.i would completely dis-assemble due to the amount of heat that the rear will see(400deg. for about 45min.to an hour?)which would possibly loosen the bearing cap bolts.and hey better to be safe than sorry.
