So last year my old scratched up stained slip fenders made a mess of my hull. So over the winter I bought a pair of large sweatpants for 5 bucks at the thrift store. I stretched them over the fenders and secured them with some wire at the bottom. They covered up my tired looking fenders and did a great job without marking up my hull or squeaking over night.After a season of use they still look great and I will be using them next season.
