[Iron Horse]

I have a piece of shadecloth i use for the same purpose it also keeps the sun off the dash when it is parked . Put an eyelet in each corner and tie the top close to the roof and tie the bottom forward to the loader frame etc . This deflects the stones and does not rub the glass . You could also make a cut out in the shadecloth to go down the sides of the bonnet to protect the lower glass panels (the shape would look like a toilet mat).
