I’ve just had a problem with the near side rear indicator failing due to water ingress. I’ve dried that out and it’s all good. In doing so can see that some water has leaked on the rear seals on the lights. It appears to have run down the inner boot channel. It’s not s huge amount but the boot channel is dirty where clearly some water has been running down. It appears to be from the top corner of the boot lid where a couple of seals join. See pics. Anyone any advice on a cure? Cheers
