I advise you to cover your windshield wiper blades from the hot summer sun or they will be ruined by UV rays from the hot summer sun. I use winter pipe cover insulation and cut it to size with a pair of scissors to where the insulation covers the full length of the wipers. Saves me from buying new wiper blades every year. That Southwest sun is very harsh. My last trip to the Southwest the sun shrunk my windshield seal. I had to buy a new seal over the winter for my RV! A new outside windshield shade cover is in order next for me.
