Yes, I used the betalink cleaner that was included in the kit. I cut an old white t-shirt into small ~3X3" pieces so that I would not use all of the cleaner up. You can also control the cleanup better. I recommend you wear disposeable goves while using these chemicals as well (get ones that are chemical resistant).

I taped (painter's tape) my lip down very carefully so that it would not move. After doing it, I saw another thread where the OP used a set of small clamps to hold the ends of the spoiler down. I wish I had seen that before because the spoiler has a little curvature to it which causes the opposite ends to not rest completely flat on the trunk; tape was not strong enough to hold it down. Not a big deal but would have been nice to know ahead of time.

It's better to ask a question and be informed than to not ask it and make a mistake because of an incorrect assumption.

I put the betalink all the way around. I recall that the mounting surface of the lip goes all the way around and I just followed that area. My thought was that if you did not seal the entire area, water could get in there and have a tough time finding its way out.

Awesome man, thanks for the tips! And that's good to know about the clips I would have never thought of that. Do you remember did they just leave the trunk open while the glue set since they were using clips on the end?

I recall that the clamps were spring clamps but don't recall how they positioned the trunk. I would wrap two semi rigid foam blocks in a towel and place them between the trunk and the quarter panels so as to keep the trunk from fully closing, and leaving enough gap to use the clamps without touching the quarter panels.

You should do a few dry runs to make sure you're familiar with how the lip goes on the trunk and to get your steps down before using the betalink. Keep in mind that once you put the tape and clamps on you won't be able to clean up under those areas. I held the spoiler in place by hand, did all my cleanup, and then used the tape to keep it in place. After 24 hours, the betalink solvent will still work to clean up small areas as needed but it will be much tougher than before the adhesive cures.

When you apply the glue, keep the bead of glue in the middle of the gluing surface (~1/8" or so from the outside edge of the spoiler, i.e., the visible edge). That way, when you do apply it to the trunk, you'll have less squeeze out and more of the lip will have adhesive on it.

I installed the spoiler right around 24 hours ago and I just went and removed the tape and there is still some wiggle to it when I press down the spoiler. Is that normal? I assumed that it would be rock sold with using beta link, I'm getting kinda worried that I might not have gotten a good a bond to the paint for some reason.

With Beta Link the Spoiler is rock Solid.
You applied only a thin layer right?
This is not silicone. You just need only a thin layer between the spoiler and trunk.

When I installed mine I cleaned with alcohol the trunk and also the solven it brought. Also the spoiler I cleaned it with solvent, alcohol and also sand it the inside so the beta link had better grip.

yes I applied just a tiny amount, I used a syringe to apply a then bead along the edge. I was the truck with dish soap to strip any wax, then let it completely dry, I followed that up by wiping it with the beta link solvent. I didn't clean the spoiler with anything prior to apply the beta link, but I did give the area a slight sanding to roughen it up a bit with the sand paper provided in the kit. The main areas that I notice it being loose are on the corners. I tried to clip it, but all the clips I used wouldn't work so I just applied tape and taped it down as tight as I could.

I just had it down with painters tape I'm a overnight and that was it. I also never tried to move it like in 48 hours. Then it was rock solid.

Don't touch it for the next 24 hours. Take the tapes out and check it. If still moving, go to a body shop.

Great idea for using the syringe

Thanks, great tips

One thing to note, maybe don't leave tape on the bottom painted areas on the udnerside of the spoiler in the middle as some of the tape became trapped under the betalink!! I had to score it lightly with a razor blade then use the trim tool to remove with and then solvent and quick detail.
I am about to install my own spoiler, but I'm having a hard time picturing what you guys mean by taping up the trunk with painter's tape. Does anyone have any photos of this?

Do you mean that you run tape across the front edge of the spoiler where it meets the trunk so that half the tape is on the spoiler and half on the trunk, sort of like a "hinge" between the spoiler and trunk? I suppose I could see how that would serve to keep the spoiler in the correct spot and would prevent Betalink from squirting out onto the top surface of the trunk, but would still allow you to squirt Betalink under the spoiler where it belongs.

Am I picturing this correctly?

Also, can Betalink be purchased at the dealership?

Which tape do you use from 3m? I was looking at their vhb line of tape not sure which number to get.

I ended up installing using 3M tape. It was pretty straightforward and came out nice, but having done it, I would probably use Betalink if I had to do it again. For one, I can't imagine how it would be harder than tape. I was really concerned about misaligning the spoiler, but it's pretty easy to line it up. I test fit it first and used blue painter's tape to mark where the edges should be on either side, making little adjustments until I got it dead on. This made it very easy to nail the placement when I did it "live."

Why would Betalink be easier? Because it was a bit of a PITA to line the tape up on the spoiler. You have to make sure it's stretched thin enough so there is no gap between spoiler and trunk. You also have to make sure it's far enough back from the edge so you don't have take sticking out. All in all, it seems to me that Betalink would be easier to put on and would allow you to wipe up any reside that squirts out.

There is the concern about getting excess on the car, but you could mitigate that by putting tape down on the trunk close to the edges of the spoiler to catch excess Betalink. Plus, it's not like the stuff dries instantly; you have some time to wipe it up. And, of course, the Betalink is guaranteed not to fly off at high speeds. I do worry about the tape.

Cliffs: Installed with 3M tape. Went pretty well. Would do with Betalink if I had to do again.

When I investigated using the 3M tape I recall finding instructions from 3M stating that you should not stretch the tape when applying; stretching it reduces adhesion. If you look at the stock spoiler, the tape is not stretched at all and the spoiler sits above the trunk slightly because of the tape. 3M does make the tape in different widths and thicknesses. Did you get the thinnest tape possible?

Just installed my spoiler using 3M...it's been a few hours and I can feel it becoming more and more solid. No gaps, even up close - I'm satisfied. If anyone's curious about the tape's cure time, I found this on 3M's FAQ site:

Immediately after an application is made, about 60% of the bond strength is achieved. As the adhesive continues to wet-out the surface, you can expect the bond to be at about 75% - 80% after 24 hours. After 72 hours, 95%+ of the bond strength is achieved. The bond will continue to build with time.

to those who uses betalink did you guys just apply the glue at the back portion of the wing or at the front as well? it seems hard to use it at the front since it barely touches the hood. can i use 3m double sided tape in the front then betalink in the back instead? any help would be appreciated. by the way i got an 09 E92. THANKS

I used beta link all around the spoiler so it's sealed.

+1 on 3M.

I used 3M to install the spoiler on my E36 M3 8 years ago and it's perfectly solid even after seeing 140+ many times. Do not believe the skepticism on 3M, while not permanent like BetaLink, its more than enough and do you really want to permanently mount your spoiler? What if it gets damaged, cracks, oxidizes, etc...?

I recently did the install…I initially wanted to just do 3M Automotive Double-sided tape, but after reading all the reviews I decided to go with Betalink. Let's just say I'm so glad I did. Feels so damn secure and doesn't move a bit. If you take the time to prep and do this install correct with Betalink, the results are the best possible IMO.

Thanks
To Remove spoiler:

1. Clean the area
2. Use heat gun to heat it up (make sure not to damage the paint; do it in sections, 3-5 inches at a time)
3. Use fishing line to separate the spoiler form the trunk
4. Use 3M adhesive remover to clean the trunk

To install CF spoiler:

1. Use BMW Betalink-K1 (BMW pn 82-69-9-408-866)
2. Read directions


It should look like this when you done !

Reviving this thread, as I am about to install an OEM Performance Spoiler in the next week or two.

I ordered the betalink.

One question is that I was really surprised when the spoiler arrived that it was sooo light. Additionally, the back edge of the spoiler (more towards the rear) has a little edge to add the adhesive and glue down, but the front edge (where there is a more severe angle) has a minimal edge/face to apple the adhesive.

Is this normal? Is there enough of an adhesion surface to hold this thing? I imagine there is since many people have installed successfully, but did anyone else have this concern?

Thanks all
