I have used . .
Thompson's waterseal with success. The bimini I used it on was 11 years oldIt was just worn, no obvious rips or tears. I bought a can and transfered about a quart to a plastic spray bottle (the kind you use to mist a plant) and applied it liberally.If you have any small rips or tears, I used clear rope whip.Hope this helps,Chriss/v Tidesong
