A high-pressure wash can, under certain circumstances, be brutal on a factory paint job. However, it's unlikely IMO that it was the high-pressure water alone that caused your paint to pop off. I've witnessed first-hand the damage pressure washing can do to a paint job. But 90% of the time there was some type of damage to the paint (small chips, cracks,etc.) that the pressure washer took advantage of and made worse. If your vehicle is a newer vehicle and the paint was undamaged before the wash, then I would say that the paint had extremely poor adhesion to the plastic bumper. Perhaps it was poor quality paint from the factory or maybe the bumper had been repainted poorly after a small fender-bender. I can only speculate about the many possible causes since I don't know any details about the vehicle in question. What I do know is that you are in a crappy situation that could get worse........ even with a spray from the garden hose if you aren't careful. My advice would be to fork over a couple of Benjamins at the local body shop and get that bumper sanded down and repainted professionally. Then when you get it back, think twice before taking it to the local service station car wash!:wall
