Hello everyone,

I recently have had some trouble installing a spoiler, due to lack of adhesive power. I have had to redo trying to get the spoiler on three times, with the hair dryer and floss method. Sometimes I do not even need to use that method and just pull up on it, and it comes off. Apparently the two ends will not stick to the tape. I have tried three different types of 3M tape and nothing is strong enough to hold down. I have tried the automotive one, industrial, and unfortunately I forget the last one. So, I am here to ask you all what is the strongest tape on the market? Something stronger than the 3M tape, because nothing seems to be holding this **** down. Price is irrelevant right now, all I want is the STRONGEST tape available.

Thank You

3M is the best
You need the right thickness
Yours looks too thick
Some spoilers have a slight recess for the tape
You want it slightly thicker
Clean all surfaces with alcohol
And pre-heat them before taping

Wurth might make tape

This is the AMG spoiler, so what tape would you recommend? I used this gray one that came with it, but it seemed very thick because I could see under it.

When you say pre-heat, which parts are you referring to? As well as the alcohol; Do I apply some to the spoiler where I am putting the tape on it?

Ingenieur

Heat all surfaces that get tape Warm not hot
Same for the alcohol cleaning

Wurth makes it
Go to their website

You want very thin like 1 mm or less
Wurth makes a tape you expose
Then stick the part on
Remove the part (some adhesive stays on it)
Then place on car

I use a propane torch to completely dry and warm up the surfaces, just be careful, and you'll be fine. just foamy 2 sided tape from any auto parts store should be fine. A hair dryer would work as well

Ingenieur

I would be nervous using a flame
Heat gun at a distance or hair dryer
Just warm to the touch is good

3M makes various thicknesses
From 30 mil to 90 mil
0.75 mm to 2.25 mm and in between

Do you have a picture of the contact surface of the spoiler?

Mark with masking tape to make sure you are aligned before you put the part on

Have a helper to hold one end up
Place one end down making sure you are aligned and work your way to the other end

On the car?

Also, I don't understand your Wurth Tape. It's not like the 3M tape?

Ingenieur

No the part that sets on the car
The contact surface

You said you didnt like 3M
Wurth is a German equivalent
It is similar

w204_Generic

No I do not have a picture of the spoiler.

I have always used 3M UHB ( Ultra High Bond).

Surface prep is most important,make sure it is free of grease,wax,polish and other types of glue.If you can scuff the underside of the spoiler it helps as well.

Hope this helps.

Is it an aftermarket AMG spoiler?

It could be the quality/fitment of the spoiler, preventing it to adhere to the trunk...

I used the grey 3M automotive adhesive tape and its on there good.

Well you can always epoxy it, but it's a ***** to get off. I had a body shop install my carbon spoiler and that's what they used. Couple years later it faded so I had it removed and it was very hard left a few dents (not visible) where they pried it off. Got another spoiler on there now and 3m tape worked fine. I noticed the tech taped the thing down with yellow tape over night to hold it down. Maybe you should try it.

WRATH

Epoxy is super strong and like mentioned can cause damage during removal.I would use that only if a permanent bond i required.

Along with the 3M UHB i mentioned above you can also use some RTV silicone in spots and tape the spoiler down,leave undisturbed overnight and you should be all set.

Thank you for all your help guys!

It's a JBSPEED aftermarket AMG spoiler.

Also, I don't think I cleaned the surface properly. Can someone please do a followup on what I should do regarding the installation?

Ingenieur

It's all been said

w204_Generic

Yeah but your telling me you want a picture of my spoiler and the way you word things is a bit odd.

Ingenieur

But yet I know how to put a piece of plastic on a car with tape

Go figure

Ingenieur

Go to 3M website
They have detailed instructions
Basically

Select the correct product: they tell you how to

Clean: they use alcohol wipes

Warm surface: they recommend a heat gun

Align and apply pressure
Tape it down if it lifts

Let set for 4 hours


With all the resources available these days: websites, etc., that instructions can be found on I'd be embaressed asking for help on something so simple

It's not like building an engine lol

Our educational system is broken
Please do not tell me you're an engineer lol

Word it right next time and maybe I wouldn't have such a hard time putting a piece of plastic on a car with tape. No I'm not and engineer I'm actually 17 years old. First time owning a car, first time modding a car, so obviously I am going to have a hard time buddy.


And I actually am using a website for help, it is known as MBword.org, you should try it out one day if you need help, you wont be embarrassed.

Get some basic reading comprehension and organized thought process

And do your own research and work rather than expecting others to give you a magic solution to a problem most children could solve

So you're basically saying anyone who asked a question on this forum, including the questions you asked yourself on here, is an idiot? From my understanding, it looks like YOU are the one that needs to use common knowledge before you become a coach and yell at me for asking which tape is the strongest.

Now before you get all butt hurt and come up with an idiotic response, I suggest you show me the forum rules where is says in bold font, "Questions are Never Allowed to be Asked on this Forum."

Enough with the bickering already. Make sure it's dry using some sort of clean heat, you can see the paint actually "sweat" if the surface is cool when applying the heat, and if it's clean, it will stick like crazy. I will admit it is tough to get the placement right so it sticks to both vertical, and horizontal planes evenly. Maybe some sort of reference lines with a non permanent marker prior to adding the adhesive tape would work good. to see exactly where it needs to land.

w204_Generic

Alright thank you.

The alignment seems to be not an issue, as it is perfect right now. The problem is it just will not stick so I will have to give that a try!

Prep the surface with alcohol or 3M tape adhesive promoter where the double sided tapes goes (on the spoiler itself & on the trunk).

Just use 1 large strip (or 2 max) on the top & 1 large strip on the bottom of the spoiler. Align, and pull the film out slowly from one end to the other by pressing down on the spoiler.

P.S make sure the spoiler is not warped. U can check by test fitting it w/o tape. If warped, the spoiler will never sit correctly.

Alright and my last question would be which type of 3M tape should I use for the installation? I'll be trying the 3M again, because I most likely didn't prep it correctly.
