Argh, replacement door seals, black or 'Sonar Blue'??

I'm going nuts with this.

I'm looking to replace the door seals on my 2003 D2. The missus is getting fed up with the wind noise and we're driving from Essex to Cornwall next weekend.

I've looked in other threads but can't find out why I can only find OE ones in Sonar Blue not the black that mine are?

I'm looking at OE as I'm guessing they're 'shaped' as opposed to non OE ones that I'll need to cut?

Any ideas??

Failing this I'll be going to B&Q for some stick on draft excluder!

Had a quick look on Microcat - if it's the right seal the part number is CFE500450, but a google for that doesn't show anything. Microcat indicates it has been superceded but I can't find by what.

I'd ask a dealer direct - they may have updated information.

One other thing - I had a similar problem and it was cured when I replaced the door frame - the previous one was loose at the bottom where you can adjust the frame to get a tight seal.
