So I just ordered an eBay trunk spoiler someone on this forum recommended in #755 Steel Gray M. I've read through this thread a number of times and I'd like to summarize below. I'm much more a visual person but I have not seen any pics of the process, specifically the silicone application.
1. The key to a good spoiler application is to make sure the trunk surface is clean. Use alcohol to clean the trunk surface and the spoiler surface.
2. A properly contoured spoiler that matches the trunk line is key and hit or miss from the manufacturer.
3. From the factory the spoiler is tapped NOT glued. 3M VHB is the correct tape.
4. Some have had great success with just using 3M VHB and taping down the the ends and entire spoiler every 10 inches.
5. Some have used silicone on the edge of the rear of the spoiler and used the same taping procedure along with possibly masking the body for overflow of silicone. (I'd love to see a pic of this).
6. Heat seems to be a good thing for application. Heat up the tape, spoiler and trunk edge prior to application.
7. Let the spoiler sit for 24/48 hrs. taped down after application.
Please let me know if this all makes sense and is accurate. TIA.

2008 G6 Convert
Glue or replace
Have a 2008 GTP G^ convertible, the rear spoiler has been, "spoiled" by someone who thought it ok put their luggage on my trunk at an airport parking ramp.
The plastic where the screws are mounted to the spoiler have broken from the spoiler. SInce I don't want to spend upwards of $1000 to replace this accessory, would it be recommended to just glue the spoiler onto the trunk? The LED works just fine.

428Street (and others who contributed to this thread) - these were perfect instructions! I replaced the white spoiler of my c63 today with a carbon fiber spoiler. All in all, took me about an hour, maybe a little longer since I was taking my time
Before (with white spoiler):
With white spoiler
During (spoiler removed and cleaned up) - NOTE: To remove the residue, I used the "3M™ Stripe Off Wheel 07498, 4 in x 5/8 in with Mandrel (3m 7498)" and it cleaned things up *perfectly*. I used rubbing alcohol to prepare the surface of both the trunk lid, and the spoiler. I used "3M 1/2" x 15 ft VHB Double Sided Foam Adhesive Tape 5952 Automotive Mounting" as my tape and it's sticky as heck!
After
