I had a doubt as well on my car , but after using the machine it showed perfect reading , one of my friend who is a dealer , said my 1.6 fender is painted , even though it’s not , you can easily tell it’s original, Baat nahi manta, even though the device is showing a perfect .11 to .12 , laikin phir bhi kehta hai nahi paint hai , so I wouldn’t go on desi tarika, sometimes factories sai paint asa ata and it seems painted , I’ve bought a Yaris last month , brand new , and it’s trunk had pin holes , I was pissed , but again device showed perfect reading ,
