I'm not sure why it has worked with mine but it did quite well over twelve months ago and still looks good. It is only the central surround (not the outer one that clips into the dash) that has started to grey up, nor the moving centre parts. I pulled the vents out of the dash, treated them with armour-all and just left it to soak in for a few days. My understanding of plastics is that they should be almost impervious to absorbing anything, but I guess time must change that in these instances?

What have people used to replace the deteriorating foam/sponge strip in the vents (make them a bit more stiff and hold the direction they are pointed in)? Can you buy a similar thin/flat single side adhesive strip anywhere anymore (Clark Rubber etc)? I know it is a bit anal but just makes them work properly again. 3M used to do something for aircon ducts that used to be available at Repco that you could pair down a bit, but to date I've just used a couple of layers of cloth tape.
