The number of stone chips and debris I've acquired on my bonnet alone from 50k miles driving, are no where near great enough to warrant having that monstrosity strapped to my bonnet. I have about 5 chips.
That can not be the real reason to fit one, surely.
Are they strapped down pretty secure to stop cack getting underneath them?
their not supposed to be left on for any length of time, mines will be used for long hauls only
