The preview owner must using a screwdriver or something that he put bunch of deep mark into the rear diff housing . I was going to use felpro gasket . But I think right stuff gray properly work better since it fill up those deep mark up
Mine look worse then that . The housing suffact is having deep gouges . I change fairly many rear diff and this the worse I seenBefore:

Before/after. I accidentally instilled some gouges on this upper pan while removing the lower pan. A few seconds with a brown 3m roloc disc smoothed the gouges fairly well. You may want to consider doing the same.
I wouldn't take a Roloc to that or any engine or transmission for that matter, the abrasive dust generated by these things can severely damage bearings over time, I wont even use one under the hood for any reason. If the parts are being thoroughly washed and cleaned afterwards like a bare block or housing that's different.Before:

Absolutely......I’ve always used a gasket and RTVWhen in doubt I use the gasket with a thin layer of RTV on both sides of it and have never had a leak with that combo.. That said I think you'd be fine with RTV only. I've never had one that clean before reassembly!
Same here. Every time.Absolutely......I’ve always used a gasket and RTV
Never had one to leak

Drain and fill diff covers are the best for sure !Have not used tube goop on a differential in many years …
GM has a great gasket and the Jeep has drain/fill plugs …
I contained the dust, if-any. The entire process took under 3 seconds.I wouldn't take a Roloc to that or any engine or transmission for that matter, the abrasive dust generated by these things can severely damage bearings over time, I wont even use one under the hood for any reason.

If anything I would just use a very fine file to dress the area to remove anything proud of the surface and use RTV, you could also swipe a bit of JB weld on the mark and a couple of strokes with the file with restore the surface for a gasket.
