they say they spray it with diamonds, the diamonds are propably incredibly small industrial diamonds which would find it imnpossible to take a chip out of the paint. they probably do 'blast it with diamonds' because their legal department wouldnt let them advertise that without proof, but as i said, if the diamonds are the size of a grain od sand, the test's only benefit is that it allows them to place it on their advertising propaganda. this is the only issue that puts me off the car.
