you cant really escape a good wash and wax/polish every few years....
i use the meguires wash/wax product in between, and its great....but the finish isn't real long lasting...
i wash and wax mine myself sometimes....but honestly im too lazy and busy anymore....i let me local detailer hit it with his crew once a year....hand wash with full hand wax/polish.....bout 150$.....worth every penny...
