Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I mentioned the in the 3rd reply to your original postsweet will give that a try might even go past panel beaters see what they think
You seem fixated on overspray on your VIN plate yet don’t know what actual damage was done to your new car.,... I’d think your car has been damaged and repaired/resprayed at some stage rather than a factory paint QC issue.
Note that crash repairs can even occur to new cars, pre delivery, where shonky dealers may not say anything... If you bought it new, I’d go talk to a repair/paint shop and get their advice and a report if in their opinion it’s been repaired. Then if it has been repaired I’d take it up with the selling dealer.
Yes I have seen this with my own eyes. At Strathpine Brisbane while out the back of this tyre place they was a compound ( A barbed wire fence) that was owned by a panel beater (out the back from prying eyes)and out there there was at least 20 new cars that had damage nose and rear damage. Some were severe, some were minor. This was the VE series of Cars that had the stickers on the windows from new. THEY SHOULD NOT BE ALLOWS TO SELL THEM AS NEW!!!.Cars can be damaged between coming of the assembly line and in transit to the dealership so a repair could have been carried out in that time
