VW Scirocco mk2 spoiler gasket set. available for early small spoilers and the later large spoiler equipped vehicles.
The rear spoiler is a known issue for water ingress. Over time the oem gaskets shrink and allow water to pass under the spoiler and into the boot.
The gaskets are cnc cut from 3mm foam and have a self adhesive rear backing.
These can be fitted to either the boot lid or the spoiler but id suggest attaching to the boot lid would provide more protection against ingress.
