I have a veilside 1 wing . they've drilled a few hole for the install and everytime I wash the car or rains, my trunk retains water and always heavily drips, with me having to constantly wipe it down. anyone else with this issue?

 

Try using that clear window caulking silicone stuff on the underside of the hatch, to seal the bolts and nuts.

 

I'm right there with you man. I've got a nismo wing (the previous owner put on) and my hatch seems to hold a lot of water. thankfully none of it leaks into the interior, however I'm going to have my body shop guy either remove the thing or remove, repaint and seal that thing.

 

I've got a V1 as well, and it does the same thing.
Makes the hatch heavy as all hell as well!...and it takes forever for that water to evaporate. Even turns to ice in the winter.

Don't really know what else you can do except take the damned thing off and then put it back on, sealing all gaps with silicone. One day I'll replace the hatch with a cf one, and I'll make sure the spoiler goes on right, but until then, I'll just deal.
