The power of a pressure washer

Cleaned my car yesterday and as I was jet washing the front end some of the paint came off!!!! Very angry! Seems the more I try looking after it the worse it gets! Tempted to cover it with some sort of decal :,(
 
You were either to close with the nozzle or had the pressure on to high you only need to loosen the dirt not blast it off with the jet,
 
I feared this from the title!

Never get close to the paint and spray from at least a foot away.

Hope it's sorted but I wouldn't mention you jet washing it to them.
