It may be better not to stick a tw**ts sticker on anthing that don't belong to you (other than buildings etc) without checking first
Not everyone is going to see the 'funny side' if there is one.
May sound boring but I would not want one stuck ANYWHERE on a car or bike etc that belonged to me thanks.
Hence I added some caution to that post.... sticking things on cars in places that it will not do any damage, in my opinion is fine, and part and parcel of driving through the shampoo bar when theres a motor race on....
Suitable locations include windscreens, windows, and over the top of BMW badges....
Unsuitable locations include directly onto paintwork, and anywhere where if you had to scrub it it would cause a hassle.....
I too would be most hacked off if someone stuck something to my car in a location that would damage it asthetically, but in an area such as the windscreen....well compared to the ACO campsite sticker, its likely to pale into insignificance.....
