Pressure washer taken layer of paint off!

[Guv]

My car has been pressure washed and it's fine apart from on the bonnet where there are now patches where it's taken a layer of paint off!

Why has this happened? and will I now need it resprayed to get it sorted or will t-cut help?

Bye bye clearcoat. Was is a Punto by any chance?

Were you pressure washing perpendicular to the panel?

Thanks for the replies, I'll get a quote for having it sprayed.
I've learnt my lesson, the pressure washer can stay in the shed now!
