I live in Nova Scotia, Canada and am gone away for a week or two at a time. When I return home, we have normally gone through some cold and warm cycles in the weather and the snow in my driveway is usually ice or very hard snow. I have used my snowblower a few times this winter and the area around the impeller (the circle) is very worn from using it a couple of times. Paint is gone and heavily scratched. Would a rock guard or bed liner paint help this before it puts a hole there or what other suggestions would the good people of this forum suggest.
