Front Drive Shaft Update

[C-Mack]

Most likely the coating is applied to all OEM cv-joints/shafts as a sort of preservative during manufacturing until such time the shaft is either put into service on a vehicle or spends an extended period of time as replacement part in inventory. Sort of reminds me of new old stock parts they used to pack in cosmoline. Once exposed to the elements for a while it sort of dries out and flakes away.

Cosmoline is a pain when the part has been wrapped in that crepe paper stuff for a few decades.

Maybe the waz keeps them healthy for a little longer than otherwise

Anti-Ozone Agents for Rubber​

While waxes provide surface-level defence, anti-ozone agents for rubber also include chemical stabilisers that inhibit ozone reactions within the polymer matrix. These agents are often used in tandem with wax additives to create a multi-layered protection system.

Common synthetic additives include:

• Paraffinic and microcrystalline wax blends.
