I recently returned from northern Ontario to find the front of my truck absolutely covered with bugs, flies, mosquitos. I spent great effort to remove them with hot water & car wash soap. I was able to remove quite a few but there are still many marks on the bumper & grill. Is there a product you guys use to remove these insects without damaging the paint? I'm planning another northern trip soon & I'm considering a bug screen for the front of my truck. Perhaps a bra? Advice on a screen would be appreciated. Thanx
