Wonderful, grippy, but gooey to apply - super great adhesion - but absolutely need humidity such as East or West coast, near water, Great Lakes or humid Georgia. I live in Colorado and it is still gooey on my sailboat - called the company - they said need 50-60 humidity or it won't dry. Used in my bathtub and I had to leave hot steaming water in the tube twice and it adhered perfectly. Otherwise would be 5 stars in a humid climate. 2 stars for Colorado - but it's not chemical reaction for drying - it's reactive to humidity.
