This is a disease that is probable caused by too much sun and not enough care(similiar to sunburn) the paint is pealing off pretty much like your skin after sunburn, It is not the color paint that is so noticrable but the layers of "clear" that are coming off. My 745i is a victim and also has the dreaded "dash cracking" from it's years of basking in the warm Florida baking sun. The paint has to be stipped down to bare metal to be repaired basically. Being in New England this sun poisoning is rare but we are subjected to cars having overdoses of salt which leads to premature failing of the metals be it frame rails, shock towers,quarter panels,doors etc. Hope this gives you ideas of diseases and poisons jim
