Anyone know where i can get this weather stripping gasket for my spoiler? I removed it to go wingless and buffed and wet sanded the hatch and i dont wanna re f it up if i want to reinstall it again.
I'd prefer the oem solution.

Have you tried JNZtuning.com?

They no longer make that gasket, it's not possible to purchase it from any OE dealer. I tried when I installed my CF spoiler... My solution, I went to Michaels/Hobby Lobby and bought that black felt/cloth material, cut it to fit, then installed it on the underside of the spoiler so it didn't destroy my CF hatch. It worked out well and I don't get water in my hatch so it does a pretty decent job at keeping water out too.

Alright felt it is. Did you cut it in the same form, or did you just do a bigger piece that covered the whole bottom mounting side

I laid the spoiler down on it and traced it then cut it out as one solid piece under the spoiler.

I did pull my spoiler off a few months back and went wingless at the track and there were no marks left from the spoiler on top of the hatch after 3yrs.

How thick was the felt? Like the 3mm stuff

Not very, just what they sold off the shelf at Michaels.
