Hello Folks,
I stumbled across a really excellent source of youtube videos by an American C4 owner. Too often I see "wash your car" videos by amateurs that suggest poor practices that will kill the finish of a show car.
I have been using a method it turns out almost exactly as he has described for years, which he explains in a very detailed and IMHO excellent 18 minute video. Importantly he explains
why he performs each step so you can understand the benefits of following the procedure. He has 1.3M youtube subscribers
.
If this prevents even one scratched car I have succeeded
