i would agree with you guys to an extent! the extent is this, those magnets barely stick onto fridges with 1-2layers of paint so how would it be when there is etch primer, primer, colour and clear (and im talking from factory. but like my car where iv put 2layers etch, 3layers primer, 5layers colour and 3layers clear... you recon the magnet will stick anywhere? what if the car has been painted on top of old paint (colour change)
thats why i said to use a good magnet and be sure not the scratch the car
