most if not all will make you bring the wheels unmounted so you will have to bring them to be dismounted, then the wheels to the coater, pick them up and bring that back to be mounted. its a pain in the ass but well worth it if you have a way to transport the wheels while the truck sits.
the coater i use is very good and has gotten parts done for me the same day ive dropped them off. im going to ask him to do this as i will need the truck ASAP or ill have to wait till spring so i can drive one of my other cars while the wheels get done... winter sucks here.
