Adding a spoiler to a Mercedes C300 or any other vehicle is easy and adds instant style! Today I’m going to show you my installation of trunk spoiler on my 2015 C300 W205 model. This is a pre-painted spoiler from CarID.com but there are other websites you can get this too. This spoiler is the larger version so it’s a bit different than the factory spoiler.
The first thing to do is mark the center point of the spoiler. Fortunately there are lines under the spoiler that work as a reference where I’ll mark the center with tape. The great thing is that I can use this mark to line it up with the center of the Mercedes star on the trunk.
I also bought some 3M double sided molding tape to replace what came on the spoiler. I got the 3M Molding Tape which is half inch with product number 03614. The reason I bought my own tape is because I found that the tape that was already installed on the spoiler wasn’t very sticky. Plus the included tape was attached at the wrong spot for the back of the spoiler so it didn’t even make contact with the trunk. So I just peeled off the old stuff and cleaned the underside of the spoiler. Then just stick the new 3M tape to the edges of the spoiler. Just make sure that you get the tape right on the edge of the back of the spoiler. That was the part where the original tape didn’t make contact with the trunk. Just go slowly and follow the curves with the tape. The better job you do here the better the spoiler will stick to the car.
When I was done I added two tape strips on the part that will attach to the top of the trunk for a bit more security. And before installing I cut and split the protective layer in the center of the spoiler shown here exposing a bit of the adhesive. Make sure you clean the trunk surface and wipe with a bit of rubbing alcohol first. I was able to line up the center tape mark with the tip of the Mercedes symbol. Lightly stick the center of the spoiler down onto the surface of the trunk and look at the ends of the spoiler to make sure it’s evenly spaced.
When it looks good start to slowly peel off the plastic off the tape. When you’re peeling just pull a little bit at a time and press the spoiler against the trunk so it sticks. Pull a little from the top and then do a little from the back. There’s no rush so again do this slowly.
To get the best results do your installation on a warm day. I had my car out in the sun earlier and it’s cooled off a bit but at least my trunk isn’t too cold. If you’re doing this in the winter you can use a heat gun or hair dryer to warm up the surface of the trunk. Keep pressing and applying pressure to the spoiler as the tape is peeled off.
When the spoiler is attached just go over the whole area applying pressure with a cloth just one more time before finishing. This spoiler looks great on my C300 and the color match is right on with the Metallic Gray. If you’re color matching your spoiler, you can find your body color in the door jamb here near the VIN number. Mine is C755 for Metallic Gray.
At freeway speeds the spoiler seems very secure using the 3M tape. I don’t think I’d be as confident using the tape that came from the factory. If you’re ordering a pre-painted spoiler keep in mind that there will be extra time in shipping because they actually paint these as they’re ordered. My last bit of advice is that if the spoiler didn’t come with 3M tape then replace it like I did.

great video - thanks for posting!!! Going to put my spoiler on my E350 right now! Already bought my 3M tape! Cheers!

[@TheRenderQ]

Nice! My spoiler has been on more than 2 years and still holding up pretty good! One thing I’m seeing on mine is on the left and right tips on the ends… they’re lifting up very slightly. Maybe because I didn’t exactly warm up the tape and my trunk before sticking it on. Also the spoiler tends to have an upward curve (at least on mine) so any weakness on the 3M tape will allow the ends to lift up a bit. Other than that my spoiler is still attached on the trunk pretty solidly. Thanks for watching!

Update on how the tape is holding up against weather (heat and water).

[@khe8969]

U have update?

[@tamasmolnar7151]

It is cool!

[@familienviig2207]

Thanks for your video It was to great help

[@TheRenderQ]

You’re welcome! My C300 spoiler installation video was helpful! And just so you know it is still securely attached to my trunk since I made this video. The only thing is that the adhesive on end tips of the spoiler are starting to come up a bit. That’s the part where I have the least amount of 3M tape. At some point I’ll probably remove and reattach new 3M tape. But for now it is still attached firmly on the main part of the trunk. Thanks for watching!

[@SuperMatrix59]

I bought 3 m tape anyway. Idk how good the tape included is. My wing could be airborne and it's too late. Good vid

[@TheRenderQ]

Yeah the included tape really wasn't very sticky when I tested it with my finger. So the 3M tape is definitely the way to go!

[@atomixify]

Great video, thanks for sharing. Just one question: do you think it would be easy to remove if needed?

[@TheRenderQ]

Hey! Hopefully I won’t need to remove my spoiler but I’ve seen tutorials where people used fishing line to help remove their spoiler. I don’t know how easy it is to do that. On my spoiler the very tip on the left and right are just barely coming up so I know I can get a fishing line under the tape. But the double layer on the top of the trunk may be hard to get through. But I think if the adhesive was warmed up a bit with a hair dryer it would be easier. Hope this helps!

[@golden1944]

good info

[@TheRenderQ]

Great! I'm glad you enjoyed the video on how to install a spoiler!

Btw is this 3m "molding" tape the same as 3m vhb? Im sorry its very confusing. Dont want it to fly off

[@Fister_of_Muppets]

How did yours hold up? I just bought a paint matched spoiler for my ES 350 and was curious if you bolted it or taped etc?

[@BassGods]

@@Fister_of_Muppets Hope you used tape instead. I can't see myself drilling holes in the trunk of a nice like that.

[@Fister_of_Muppets]

@@BassGods I used tape and I drilled. I used a new step drill so besides the hole itself, there was no damage to the paint around it. Touched up the inside of the holes with paint and let it sit for a day, then used silicone as a seal in the four mounting holes when I drawed everything in with the bolts.

[@praparhmeesuwan815]

🤤the original tape it peels off /too easily🤪 🙋you made the right decision selected and used 👍👍👌👌👍👍 -SUPER STRENGTH MOLDING TAPE™

[@TheRenderQ]

Yeah when I saw how ‘unsticky’ the original tape was I knew that wasn’t going to work. The 3M tape I used was the right choice. I’ve had my spoiler on for over 3.5 years and it’s still attached. The only thing I’d do differently is pay more attention to the ends. The ends are slightly up now and partly that’s due to the natural upward curve of the molded plastic. So when you attach the spoiler put as much 3M tape as you can on the ends. Then place a heave object on the ends as you wait for the tape to get a good seal on the trunk. Thanks for watching!

[@GuruPrashanth7970]

Perfect! Does the taped spoiler hold tight even when driving super fast? How long does it usually last?

[@TheRenderQ]

I installed the spoiler on my C300 just over 3 years ago and it’s still attached to my trunk! What you saw in my video was my actual installation. For the most part it’s still holding on strong with the 3M tape. The only issue is the tips on each end. They are slightly up where the adhesive isn’t sticking as well anymore. You can’t really tell on a quick glance but I know the adhesive needs replacement on the ends. That’s because the spoiler has a slight bow upwards so it constantly has pressure pulling up on the 3M tape. Even after 3 years I’m not worried. I drive on the freeway quite a bit and it’s still attached quite well. But one of these days I may take it off and reinstall with new tape putting weight on the ends in the beginning to ensure good contact with the trunk and spoiler. Hope this helps!

[@HarryWangHungLo]

I’ve learned from my second install of a trunk spoiler is to wipe down the surface of the trunk where the spoiler makes contact with 3M adhesion promoter after cleaning with rubbing alcohol. It really sticks on years after installing.

[@barjunkies1]

Do u have a video that shows how to take the spoiler off

[@TheRenderQ]

I do not have a video on how to remove the spoiler because I’ve never removed it. But this summer I may have to remove it and replace the 3M tape. But from some research it seems that most people use fishing line to help separate the tape from the car. It might help to warm up the adhesive with a hairdryer first or do it on a hot day. Hope this helps!

[@seraal1]

How does the spoiler hold up? Any problems? Scared that the tape may not be enough

[@TheRenderQ]

Hey I’ve had the spoiler on my car about 10 months now and it’s still attached! It still feels really secure on my trunk. The only thing I see is that on both ends where the spoiler gets pointy I can see the 3M tape coming up slightly. On the ends there’s not as much surface area for the tape. Someday I might have to remove and replace the tape. But so far it’s holding on well! I do a lot of freeway driving and it’s holding up to all the wind at 60-70 MPH.

[@eatshit2863]

[@carlosmelendez8317]

Im always worried about the 3m tape degrading and the spoiler flying off one day.

[@dotta4763]

Where did you buy the spoiler from ?

[@TheRenderQ]

I bought my spoiler from CarID.com. The color matching was exact to my car. Looks just like the factory color! These spoilers are around $300. Thanks for watching!

[@leninavila4573]

Does it not fly off when ur hitting 100 on the freeway

[@TheRenderQ]

The spoiler you saw me install on my C300 has been on for about 2 years now and it’s still attached to my trunk by the 3M tape. I believe that’s how a lot of lip spoilers are attached these days. I drive on the freeway long distances quite often around 70 mph and it’s still holding strong.

[@MrMia2008]

what about washing the car or car wash will that tape hole ?

[@TheRenderQ]

It’s been about 1.5 years since I installed the spoiler and shot this video. The spoiler is still going strong! I only wash the car by hand and have no problems with it. However I do not go through a car wash though. The only thing I see is that the tips on each end are slightly popping up. Partly because there isn’t as much surface area to apply the 3M tape and also the spoiler naturally wants to bend up. But looking at it you wouldn’t be able to tell that it’s not stuck as tight right at the tips. The rest of the spoiler is attached very solidly. Hope this helps and thanks for watching!

[@MrMia2008]

@@TheRenderQ Thank you and your welcome.

[@lastsaiyan3530]

@@TheRenderQ securing bungee cords around the ends through the trunk and around will keep the corners down :)

[@mariglenkaraj7515]

Hello,do u think the spoiler will not fall using only the tape ?

[@TheRenderQ]

The 3M tape will hold the spoiler on securely. The spoiler you see in my video was installed in 2019 and it is still attached to my trunk today. The only thing I would do differently is that after I stick the spoiler onto the trunk I would use something heavy to place on both ends to ensure maximum adhesion. Currently the end tips have slightly come up about a millimeter. But overall the spoiler is very solidly adhered to the surface of the trunk. Hope this helps!

[@mariglenkaraj7515]

@@TheRenderQ thank u bro

[@thehal991]

Hi, I was considering one of these but was worried that there would be a slight gap caused by the 3M tape between the trunk and spoiler, would you say it’s noticeable?

[@nickspaulding1511]

It’s not seriously noticeable, it is a little noticeable though. I used hobby glue to kind of caulk it in place so air can’t get under because I feel like enough washes would loosen it up :/ I’d say the proper way is best long term my holds up so far however

[@shajidnoor]

Is your spoiler still on with this tape to this day?

[@TheRenderQ]

Yes! Using the 3M tape shown in the video my spoiler is still attached to my trunk! I installed it 2 years ago and it still holds on really strong! 3M tape is what’s recommended for attaching things like this to cars like carbon fiber parts and trim pieces. But for this spoiler do not use the tape that came pre-stuck to the spoiler. As mentioned in the video the factory tape wasn’t even sticky. Only use 3M brand tape. Hope this helps!

[@shajidnoor]

Fucking spoiled and entitled. Why don't you ask politely considering the guy took the time to make a very good video.

Dope! Mine's will be here next week "YIPPY" 😃 Thanks!

[@TheRenderQ]

Nice! Definitely buy your own 3M tape to install the spoiler. I’ve had mine on for about 3 years now and it’s still securely attached. The only thing is that the end tips are slight up because of the natural tendency of the spoiler to bow up. So if had to do it again I’d apply more 3M tape on the tips. But there’s not much surface area there so I may have already put as much as I could there. Thanks for watching!

[@BassGods]
