Super easy to remove, just a foam gasket that will reseal if you clean up around the light.Thanks a lot! I tried to seal the spoiler around the outside, as I didn't want to go over the troubles of removing light housing. I'm not sure if that'll work lol
The tabs themselves need a blob of silicone applied around to stop the dripping. Mine sits on an incline with the trunk facing down in the driveway, so water just pools behind the lip of the spoiler when it rains.
