You want to try living on the coast,like me,those bloody gulls are a menace,not many days go past without the sponge coming out to wipe the crap of the car,and then when I have time to wash it again.
Yep - live near the coast and get your car christened on a daily basis. Trouble is once one has found a suitable location it appears to tell all its mates. They then seem to think its funny to drop shells pebbles et al all over your pride and joy afterwards.
