My 2004 truck sits outside all year long in GA subject to sun, sap, leaves, dust, bird droppings, airborne pollutants etc. Before I purchased my 1st cover several years ago I had to clean and refinish areas of the painted surfaces monthly. With the cover, it took the "beating" and ultimately became stained, moldy and torn (from a neighborhood cat). I love the work it saves me. This 2nd one should give me another 4-5 years of protection. Will buy a 3rd from AutoAnything when needed.
