https://www.westmarine.com/buy/sea-hawk--1277-bottom-paint-primer--P018202226 Does anyone have any experience with this product. Previous owner had the bottom paint line moved up a few inches to below the boot stripe. It began chipping last season. I intend to chip/sand/scrape the existing bottom paint along the water line. Followed by this sea hawk product prior to re bottom painting the water line. Thoughts on this product or something else that should be used?
