If i was you i woul be brave and take the bump stips out of the bumper, then get a good bodyshop to smooth the recess into the bumper, have seen it done on a Euro site and it looks the tits. Worth a thought. If not try a VW garage, they may offer to spray them for you. The only reason i say this is because my mate has a 206cc, his one has black rubing strips, but the new 2003 model has colour coded ones, he is getting his updated by peugeot who offered to do it all for ?200, that is the one in Canterbury, again worth a shot
