To hold the wiper blades off the glass when storing the coach, I use two rather large pop rivets through the holes in the wiper arms. Lift the arms and slip the nail-end of the rivet in place to position the arm to hold the blade off the windshield. If you forget to remove the rivet prior to driving away the rivet will stay in place. (Of course you’ll have to stop and remove them if you need to use the wipers.) I also use these rivets when installing the sun screens over the windshield and under the wiper blades. The rivets hold the blades away from the windshield making it much easier to install the sun screen without the chance of breaking a wiper arm (very expensive to replace).

The rivets are long enough to go all the way through the arm (about 1 1/4 inch) and the rivet end is long enough for a good grip about an inch.
