Oh yes, glass coat is a must, your life will be easier and you will stay away from all wax and polishes. Take it straight from showroom for glass coating so that even minor swirls or deep paint scratches can be avoided.
I wash it with Karcher k3 jet washer machine.
Twice in a week, one time on weekday and one time on weekend. With glass coat, karcher is must coz glasscoated car can't be washed by local service station guys.
I use different cloth for rim and tyres, different for engine bay and washmitt for body.
To dry it I use water magnet towels.
