I had a look and they have "Whisper" available. It's good stuff and I think there are other threads on here about it. It's not cheap but I've been very happy with the results on mine where I've touched in stone chips on the bonnet.
Thanks for the info. I have advised my dealer of Chipex. It is three times the price of a Citroen touch up but as they are unable to supply their own I think they are duty bound to do something. They are looking into the situation and will let me know.I will advise of the outcome.
Thanks again for the info.
It is good stuff... it blends in very well with the existing paint and, whilst it will never be completely invisible, wiping off the excess during the application process as you fill the hole left by the stone chip means that it's not as obvious as just blobbing a lump of paint on as you do with other paint kits.
As I said, it's not cheap but sometimes it's worth spending a little bit extra on the DS4
I've used the touch-up paint from http://www.chipex.co.uk again for my latest DS4 and I'm just as pleased with the blue as I was with the red first time around. Not cheap, but worth the extra investment in my opinion.
edit: Chipex aren't paying me commission either! ;-)
