if this is a gen qoute,then i know why!

all the original painted cars would rust quicker,the reason is ,at the time of spraying,the suspension medium within the paint mix was thinner and polymer free,(not like modern paints),
therefore,metalics,rusted quicker because of natural electro-corosion ,where the metal particles that create the metallic effect would oppose each other causing corrosion,within the surface metal it was adhered to,
in the 70s when everyone bought silver motors,they all rusted in weeks.,cause of the shitey paint mix,then they stopped buying silver cars,hence the new phase of silverman ship,now their much better,

but fuck,
lately every ones got a silver car,im sick of silver,(mercury grey is ok) its just bloody silver, next time your out ,count the silver cars on the road.

mental!
