I used the peel away product on my bottom over the past few weeks. It worked like a charm. You can purchase peel away marine grade for $69 a gallon or go to Home Depot and purchase the 5 gallon bucket that is NOT marine for $99. I contacted the company Dumond in NY and a gentlemen there told me it was the same product, just marketed to marine industry. (for those that are thinking of using the product, you CAN use wax paper instead of the peel away paper, it is just a little harder to scrape off.My question: Peel away took off about 15 years of pain and brought me to a hardened blue shiny layer. This layer seems uniformed throughout the hull. I can not tell if this is the gel coat or a barrier coat or another layer of paint. Is this the gelcoat? If not, should I put a barrier coat on? Interlux 2000?Thanks everyone. John
