Differential fluid change
OK this is my first time doing this. I have the correct fluid and I hope the correct gasket. My question is: do I use permatex on the gasket or leave it clean?

Last week I changed the rear differential gear oil on my 2011 F150. The spec call for 75W-140 full synthetic with a friction modifier added. I used ultra black permatex on the case cover. Everything went great. The bolts on the differential are to be torqued to 33 lb-ft.
