Boot spoiler

Hi guys,

Sorry if this is the wrong section.

The boot spoiler on my car has come loose in the middle to the point where i can lift it off the boot. I see it is held in place with a very thin black rubber double sided tap.

I have tried the local hardware stores and midas but can only come across foam double sided tape, that is to thick. Anyone know where i could get it from, as i dont mind doing it myself or should i just get it sorted at the stealers?

Thanks.
