I wash my car every week or every other depending on how dusty it is. In between use detailer and microfiber cloth to wipe it down every other day. I have a whole process with sealers and waxes. I seal it twice a year that process includes removing old wax,claying compounding,polishing,paint sealer, waxing. Then I usally every month or so put a nice coat of wax on.
I live in the desert so uv protection is what I'm after out here. My car will always look brand new even my black trim. I have had a plastic license plate frame for over 13 years out here in the desert and it still looks brand new.
I always hand wash with 2 buckets at home. If I do the just a wash and wax usally takes 2 hours cure time for wax is 45 mins. If I do the long process about 10hrs hence I do that only twice a year.
