Stupid Painting Question

I just got a set of RuffStuff diff covers, and its beautiful out so I plan on painting them. A stupid question, should I paint the insides of the covers or will that come off and contaiminate the gear oil? Im probably overthinking this...

Do you paint the inside of your engine?







...You're overthinking. Just shoot the outside.

Thats what I was figuring, the oil coating should protect it from rust. And since painting the sealing surface is usually not a good idea...

Thanks for confiming that.
