Similiar situation happened when my cousin got her Euro's door resprayed.

Turned out shit with overspray and dry spots.

I took the car back to the work shop, pointed out the flaws, told them that I've been in the spraying industry for over a decade (lul I don't even look that old) and they apologised and the boss told off the apprentice that worked on it and re-did it.

Turned out perfect.

Told them that I would report them to the insurance company if they didn't abide by the request.
