Yeah, thats teh only thing holding me back from gettign rid of my heater box. and that damn rainx works for about the first 1hour then starts to fog up. i remember from my old days at Autoban that u could buy the demister kits for rear windscreens that had teh strips and everything needed. but i can't seem to find them anywere on the internet. i kept all my plastics as well. just wondering how much you have to replace for targa tas etc..? and what about the boot as well?
