This is thicker than the polyprop-Light, so it will last at least twice as long as the lightest fabric offered.  if you are looking to cover your cover on a budget this is a decent go to product.  Protect against Dust, Sprinklers, Tree Sap, Bird Droppings, etc.
We strive to give you the facts, the Truth, no sugarcoating here. Remember these are actual and or real products / materials not invisible force fields that can last indefinitely as many others might lead you believe. Always look at the fine print.
