About the aluminum differential case POR15

This is something that doesn’t have to be done, but it’s a nice way to clean up the differential, and keep it looking nice (not that anyone will see it!)

Overall, this was a great day! Very excited about getting this differential to look new again, and won’t ever be seen by passers-by! LOL
