Trunk Gasket Installation, round 3

[jp5Touring]

Redid mine last Summer with good results so far. Cleaned everything up and wiped down the gasket 

with acetone or denatured alcohol , can't remember what one.

I used the black 3M on doors and trunk.

Walmarts finest clothes pins.

Suggest you use this one. It is designed specifically for EPDM rubbers, the majority of molding make up. 

 

Good luck.

Had the same problem. The solution is to use a genuine OEM gasket (BMW 51715476161) and follow the instructions on how to apply adhesive from this YouTube video: 

 

 

The process of applying adhesive to gasket and trunk frame separately, allow to dry, and then re-activate with another application of adhesive will produce a strong bond.

BMW gasket is much more pliable than URO providing a better seal.

I would venture to guess that using office clips vs. clothes pins is a big part of your problem. 100+ clothes pins, as shown, place the appropriate amount of pressure that's evenly distributed around the trunk seal. Notice how your office clips are distorting the seal, pushing out the adhesive and causing the seal to rise where there is no pressure (causing gaps and leaks). Just saying...

Wouldn't it be easier to just close the trunk lid? so the seal conforms to the trunk lid.

that photo was about half the clips, I added the rest right and filled gaps right after this shot

Noted. I think if I were taking a run at a 2002-related project for the third time, I'd be a bit more open minded and consider failing variables beyond choice of adhesives. jp5Touring nailed it above. Clothes pins securely hold the seal in place while the adhesive sets up. Your office clips are just crushing and distorting the seal. Try clipping a clothes pin and an office clip on your fingertip, and you'll get my point. At the end of the day, it's your car, your choice of process—and your leaks.
