a common problem on e34's is the vinal skins pull of the pressed masonite backing. I investigated a solution to this today and found a very good one. A local guy to me can vacume some new material onto the masonite in the same texture and colour. It looks very neat, will last much longer than the original skins and is a harder fininsh too. Total cost $500. $125 per door. Good idea I thought. takes a week.
