I have a 2003 JTD and I have noticed recently that the bottom corner of both rear doors are quite badly chipped and one side started to rust due to small stones being thrown up by the tyres. I know this because when I open the doors the small stones are trapped and fall out when the doors are opened. Has anyone else experienced this? Have I got some sort of protection shield missing from mine? Can something be purchased? or even rear mud flaps might help. Any thoughts anybody? Thanks.
