How long does it generally take for a water spot to become a "tough" water spot?
Last Friday afternoon I washed my wheels (was going away for the weekend, and didn't want to leave the moderate brake dust). Tonight I was going over a couple places on my black car w/PB S&W and notice what I think are a few tough water spots on the hood. The S&W wouldn't do anything to them. Could I have etched in water spots after only 3 days? Car sat in the garage all weekend. Assuming they are some tough water spots, what should I use to get them out? Thanks!
