Haven't you guys heard of GPC VWAUDI in the Uk
You get the 4 window scapers for about $100 plus postage
they have lots of hard to get postable goodies
those window scrappers seem to be sensitive to the sun & are something I need to replace as well

I have noticed quite a lot of deteration in a lot of plastic & vynal components in the last 12 months on my car. T he rear decal sticker completley broke down & started flaking up over the period of a couple of months
