Look, you’ll be fortunate if another rinse is enough. My recommendation isto forget about it, and see if your customer notices, If so, bring a friend to rinse while you brush away the SH if you don’t have a WFP. Remember, that although my buddy IBS has already forgotten more than you and I will ever know about PW, sometimes his advise won’t help you get out of the sh&t, just help you to stay out of it. Right now your hip deep. GOOD LUCK!
Oh yeah, if our customer doesn’t notice, the rain will eventually get it, but they’ll probably notice.
