I'm preparing to install a Nismo rear wing on my coupe. It doesn't say anything in the instructions about sealing the base, but I was wondering if anyone, who has installed one, has used something like double sticky tape around the perimeter, with corner water outlets, to seal out dirt, and wet debris from collecting underneath.

It only mounts on 5 small bosses with thin foam cushions and it appears as though the outside perimeter, of the base, touches the deck lid all around, but doesn't provide a seal.

Thanks

 

When I mounted mine I did not seal it for poss. future removal plus theres really no reason for it, if it rains or I wash it the water will run out as I drive down the road. If theres the slightest chance you want a different spoiler [never say never] later, being sealed off would make it very hard to remove.
