Hi there,
I don't think the pressure washers are bad for cars in good shape, but the pressure jets can certainly exploit weaknesses in the paint.
If you have deep scratches or flaking due to dents/corrosion then the paint is compromised and the pressure jets can get into the gaps and make it worse.
Likewise alloy wheels are more or less all painted, what you're looking at isn't the metal surface of the alloy but a painted surface, and so therefore the same process can occur on the wheels.
I'd say youre better off washing the car yourself from now on (or paying the oik down the road to do it).
