Lower front grill mesh?

[blenkinsbob]

Having just suffered a very expensive damaged front radiator from a stone through the lower front grill; is anybody aware of a remedy to avoid a repeat, grill mesh or other. Has anybody had the same experience. Seems to me the grill bars are part of the problem as not angled downwards like the main grill. Any thoughts or experiences appreciated?

Would also be interested to know if anyone had a resolution for this? Had the unfortunate stone through the lower grille and take out my charge cooler radiator.
