I love white hats. More than that I have an issue buying them. They have never stayed white. I bought a new white hat and sprayed it. Yes it has the hand marks and the mark from the sticker but that is because I couldn’t get it clean enough before spraying it. Absolutely amazing product. My buddy came up for a member guest with a new white hat. I sprayed that as well. It was 80+ in Washington so a bit of humidity and neither of us had sweat marks on our hats or any new dirt marks. I will for sure but more product and of course more white hats. It also works great with my gray hats.
