I used basically the same on my rib; I thought for the price itís worth a shot compared to seadek! Even if it only lasts a season.
Have to say so far itís lasting very well! I use the rib mainly for wakeboarding so gets boards bashed on it all the time. No cuts or rips, stuck down really well, easy to fit (although i couldíve done a better job) & nice and grippy.
Iíve given it a scrub a few times when itís got grubby with soap and a Brush and itís come up like new again. Seems fine with dirt but Iíve got a few small grease stains that donít come out with just the quick scrub.
Iíd recommend the stuff
