Too late. No one said anything but I gave it a really light bath yesterday. By the time I washed it the car had been painted for about 10-12 days; hopefully that's long enough not to cause me any ill will.
You'll be okay. It's pressure washing after painting that is a terrible idea. Top of the paint is dry, but under the dry portion the paint is still wet and if you blast at it with high pressure you'll wash the paint away lol
EDIT: this is if they didn't bake the paint on. If they baked it, it should be 100% dry, or so I would think.
