I got them from a place I used to work, but they are available at auto supply shops etc. A common item that is used everywhere.
The O-rings are 5/16" inside diameter x 7/16" outside diameter x 1/16" (#011). I'll check this size as they look a bit bigger in the photo.

 

Yea, I'm still leaking, and I think it's due to the o-rings I bought NOT being FLAT-WASH. I can find the correct diameter o-rings EVERYWHERE I shop, just not flat wash...

Also, I used industrial-strength weather stripping (much better than the "EPDM Cellular Rubber Weatherstrip Tape"). My father works at an industrial site, and knew where to purchase the aforementioned stripping. This being said, I think it HAS to be the non-flatwash o-ring washers.

 

I just reread this post again and the washers are just plain O-rings and not flat washers. I missed emphasizing that they were just O-rings I did give the size though , #2-011 actually.

 

 

The beauty of O-rings is that they are compressed and push against both surfaces that they are between, plumbers putty is just a seal and does not push against both surfaces to any great extent.
I was going to use O-rings and a putty type of seal at the top surface of the body. I then thought that if anything leaked past the top seal it would be harder to dry so I just used the O-rings.

Please confirm if this is the thread regarding the O ring sizes for the wing


Are the washers to be flat similar to existing or a Non-flat washers Ok as a subtitute

 

Use O-rings, flat seals are not so good as they will not fit in the groove and may leak. O-rings compress easily and fill little imperfections that flat washers will not fill without the use of a sealant and some sealants will make it hard to remove the wing at a later date if they leak again. I fixed mine six plus years back and I have had no leaks.
The seal around the mounting plate is crucial and is originally a poor design. The new seal should be fitted so that no pockets of water sit under the plate. Some people have used silicone sealant but if it leaks because they did not put enough sealant in the varying gaps it will be hard to remove the plate to fix the problem.

 

Looks like my car is showing signs of leakage. After a heavy rain, I observed water accumulation between the hatch seal and the trunk inner plastic liner near the striker pin

 

Be sure to remove the trunk floor Styrofoam on the passenger side and inspect that area where water collects
It damages the PSE module and the security module

 

Got it, thanks!

 

The seal around the wing mounting plate is very poor and leads to big leaks.

 

Remove the plug on the floor as well. It will prevent pooling of water in the future if this was to happen again.

Hope you caught it in time. I ended up needing to replace my security module.

 

Ya thanks for adding this important step as I failed to post that

 

Thanks guys for the best advise!

 

What I found:

 

Wow, Does that ever look familiar. Any cracks in the Wing at the top of the supports?

 

No cracks. I believe the SRT6 spoiler strut cracks are found on roadsters, a slight design difference
