Do you do it yourself or go to an actual carwash?
I think I do it about 3-4 times a year. We park our car in the garage and don't have a real fancy one, so anymore than that is not really needed, IMO.
I really prefer to do it myself, but we live in a highrise building and I cannot seem to find a do-it-yourself powerwashing place around here. Bummer.
Are you going to watch the Transit of Venus tomorrow?
