Just curious how are those door stoppers working out for you ? Was going to order one as well but want to hear a positive feedback first.
Worked like a charm, jammed one stopper in there and bye bye rattle.

I know there are a few of these around, but I think this is the best method in terms of materials and longevity.

Total cost of materials used is probably about $0.50 lol.

Essentially, this (or something similar) is what you want to buy: http://www.homedepot.com/p/Project-...x-2-ft-R-5-Insulation-Sheathing-PP1/203553730

I tried this with a few different materials, but a lot of foams will compress over time and the rattle will just come back. If the material is too rigid it'll either transmit the vibrations to the entire deck, or just fall out. This stuff is dense enough to not deform, but still foam-y enough to absorb vibrations and stay put once in.

Materials needed:
- Knife
- Electrical Tape
- Foam Insulation Board

Cut out a wedge from the foam; dimensions are shown in picture. I trust the American friends can use Google to convert:

Wrap the whole thing in electrical tape. This is so you don't get purple shit all over your trunk when you wedge it in, and also it looks far better in black than purple lol. It's important to have the tape in the orientation shown below so it doesn't pull/rip when you wedge it in:

Wedge the wedge in the space between trunk chassis and 3rd brake light:

Here it is, not yet fully in. Play some loud obnoxious music at volumes you wouldn't normally listen to. Keep pushing the wedge in until there's no more. At final position mine is about 75% inside:

Done!
Thank you. Your post worked a treat. In addition to the wedge, I used some fly screen rubber spline that I had lying around the garage and placed it between the parcel tray/third brake light and the windscreen. The material I chose may breakdown over time, however, so far so good ??
