Make the dealer fix it to your satisfaction now, and make sure everything gets documented regarding the repair in the delivery documents so you don’t have to worry about it later.
There is typically nothing a dealer can give you now, documentation or otherwise, that will matter at lease end. It’s either fixed now up to spec or it isn’t.
But it’s hard to tell from the photo how bad (or not bad) the overspray is on the sensors. If it’s bothering you point it out to the dealer and see if it’s something their detail guys can maybe take a look at.
It looks like it was a scarf, and they painted part of the front end . The job looks good, and we do not mind but nobody covered the sensor to avoid painting black rubber gasket around it.
