The Ryno

In searching for a solid DIY for the install of the rear lip spoiler, I failed to see any dedicated to this. So, I decided to snap some pics as I added this to my new to me E350.

Here is a pic of my spoiler right out of the box:



Here is a pic of the 3m double sided tape I used as the primary adhesive.



I applied the 3m tape around all edges of the spoiler along with a few beads of silicone auto adhesive.



After thoroughly cleaning and and prepping the surface, I placed the lip where it was going to go. Once I had it perfect, I used tape to mask off one edge for alignment when ready to attach. Obviously, do this step before removing the backing to the tape and applying an silicone. Place the spoiler on the trunk, carefully aligning the spoiler to the masked tape.



After firmly pressing the spoiler to the trunk, I used tape to secure it over night.

I commend you for making a guide. While some may feel comfortable doing this project, you probably helped some folks on the fence decide to take the plunge with an easy mod. It also serves as a repository for do's and don'ts. Along those lines, did the instructions call for the silicone? What did you do to prep the car surface?

As far as prepping, I washed the area very well. I then used a mix of alcohol and water as well. As far as the silicone, the directions did not call for that. However, while in college I worked at a body shop that specialized in BMWs. We always added a bead of silicone as a preventative, especially on the corners which may be prone to pulling up.

I just received my rear trunk and roof spoiler from jbspeed. Looks like I'm going to install in the next day or so.

Smart man with the silicone. Mine was lifting up from the factory tape job. I removed and used the 3m double sided tape, still didn't hold for long. I ended up using a combo black silicone adhesive and walla worked great. I had to do it to both spoilers.
