From the moment of use (5 months on a boat in the water), it shows great resistance against air, sun, dust, and saltwater. As for the negatives, the rings for fastening have already shown signs of rust. Additionally, take into consideration its weight, which makes it not easy to use (but not prohibitive). Finally, I would like to note that I have seen fishermen cover their nets with similar tarps - something that indicates and proves its durability.
