keep the same good wash process I'm sure you guys are already using.
2 buckets with grit guards
a good wash
a good detail spray
wax or seal from time to time
yes you can also coat it to make it even easier to take care of.
you will no longer need to polish it, try to stay away from claying it but if it does start to feel rough you can use an iron remove like
Nanolex Wheel Cleaner and Iron Remover.
