What's the correct procedure in removing water marks on the hood? I have a 3x3inch area with 7-day-old water marks in my hood, i think they're baked.
  1. clay - vinegar soak?
  2. clay - step 1?
  3. clay - step 1 - step 2?
  4. clay - swirl X?
(all followed by glaze then wax)

Any recommended solution that is not too abrasive?

I read that using swirlX is ok but I have to use an orbital buffer. Can I apply by hand since the are that has water marks is only 3x3 inches?
