I have, but it's not totally fair either I now know far more washing methods to prevent them(thanks to this forum). It is quite noticeable, when I first moved back the only place I could wash my car was at one of those pay DIY places. I can't remember the exact amount but it's quite a long time, I've washed about 10 or so cars and accidentally left it in the back yard for a week and it's still working well.
