If they mount them for you just be sure they don't get over anxious with the wheel grease... Too much gets into the electric brakes and makes them non working pretty easy...

Trailer drums are not quite the "same" as automotive drums.
Trailer drums have a machined surface on the inside FACE of the drum.
If I understand the OPs post they are asking if the MAGNET face of the drum can be turned.
The answer is maybe.
This will highly depend on the lathe that the shop has, most automotive lathes are not designed to be able to machine the magnet surface.
You will have to ask the machine shop if their lathe can reach that surface..
No if the OP is talking the BRAKE SURFACE then yes, any machine shop which has a brake lathe can resurface the BRAKE surface..
Please note, though, most auto parts places no longer turn down brake drums or rotors so you may have an extremely difficult time finding a place that will be able to do this at all..
You might be able to find a NAPA store that may still have a brake lathe but most big box stores don't.
