Q: Is this rear differential lubricant compatible?

Permatex 81409 High Temp Red RTV is a Sealant. It is one the most widely used gasket compounds. Made from silicone, RTV is air curing, it seals, bonds waterproofs, fills surface irregularities, remains flexible, doesn't shrink, is relatively easy to remove, and is used as supplementary sealer with almost all low and medium temperature gaskets. It used on the gasket or gaskets of differential. Compatible is not in question because it used on the gasket or gaskets which are outside the flange of differential. I hope that this answer your question. Please let me know if this helps.
