David,
You may wash it as often as you like, which may be pretty frequently, until the paint has had time to cure fully. Smell will be an indicator. Don't wax or anything similar for a month to two months. Until that time, just wash it more often. Once you have passed the break-in period just use the time tested combo of #7 and #26. (or 3M hand glaze and wax)

Sorry to hear about the hail damage. Glad to see your trying to make the best of it. If you need anything else feel free to ask.
