My boat has a flag blue awlgrip hull. There were mineral water marks etched into the paint when I bought it. None of the awlgrip products helped restore to the original surface. Rubbed out with Prism and now have to polish by hand at least once a year to keep it looking nice. Also touching up any owies in the awlgrip is not easy. White gelcoat would be so much easier to maintain. Doubt that the next boat will have painted exterior or wood to take care of.
