With good technique (foam gun, two buckets, good mitts, easy on bearing down on the mitt or the WW to dry it), I gotta believe that frequent washing is not a problem. You might shorten the life of your LSP somewhat, but since many of us like to "freshen up" the LSP periodically, that shouldn't be an issue, either.
Heck, I just like to wash my car. I find it relaxing. Maybe I wouldn't if I had three or four to do.
