Model Y Spoilers

[Speedking99887]

Hi has anybody been successful in applying an aftermarket spoiler i have tried two now from the same manufacturer that have come loose or don't stick down properly. They are real carbon at cost a fair amount seems like the sticky isnt good enough

Has anybody purchased any other brands that actually stick down properly

Turning into a nightmare i might not bother just wondered if anybody else had similar issues

and hammered the edge to get it tight in. It feels secure.

Are you Jeremy Clarkson?

Carbon spoiler that came with Model Y known to come loose, I discovered immediately upon delivered to my house last month. Created Service Request via Tesla App but Spoiler not in stock so I waited for 2 weeks. Finally, I dropped the car yesterday & earlier today I picked it, here are before & after pics:

It looks like a differnet spoiler i.e. they completely removed the old spoiler and fitted a new one.

The ends 'detaching' is clearly an issue withthis spoiler, the question is - what is the solution?

Yes, Tesla Service Center replaced my old spoiler with new OEM, I was told the center of the spoiler has clip that is hard to remove, once removed will be close to impossible to put back.

It's off!!! It lasted just 7 days!!! I have learned some things that might help others; there is stuff I need to learn to solve this issue.

It came with tape applied to outside edges. I was concerned about the quality of this tape but decided not to try and take it off but I added an additional strip of 3M down the middle inside. I was VERY careful preparing (degreasing) the surface and to apply it centrally and believe I did a good job. Although I pushed long and hard there was a 1mm open lip of the front edge. Very soon the right hand edge started lifting. I could also see that water was getting under that lip (obviously). Today I gave a little pull on the right side to see how good/bad it was and it lifted easily about 8cm right to left. Should I try and get some glue under that right edge or get it all off? I pulled and it came off with a bit of a ‘snap’ noise but quite easily and the bonnet cleaned up nicely – no damage (phew)! I spent an hour peeling off all the tape some of which came off VERY easily. It looked like the easy bits were easy because water had got under the tape. Sat there peeling the tape off I was surprised by the amount of water on me. The spoiler is hollow and it was full of water! There are two holes on the inside of the spoiler (which were covered by 3M tape and water had got in through them and filled the spoiler. Rolling side to side I can hear the water splashing inside!
Lessons learned:
1. Fill those holes with sealant before fixing.
2. Strip of and discard the suppliers fixing tape (useless).
3. Make sure that all surfaces are thoroughly de-greased.
4. Pay extra attention to make sure that the edges they are crucial..
5. Make sure that there is no lip at the front that could allow water in and get under the tape (don’t know how to do that (thin line of sealant?))

Helpful info!

Did you find any real difference between the supplied tape already in situ and the 3M tape you added?

My understanding is that VHB is waterproof, so I would've thought it could cope with water.

 

[Pablotti]

I just looked on 3M's site for info about VHB 5925F. It says:

"Creates a permanent seal against water, moisture and more"

 

[Speedking99887]

I was thinking of glueing mine with strong adhesive from b and q mine kept coming off at leadt with no more nails or something similar it will even fit proper flush

If you’re going that route and you want to do it properly you could buy a specialist two part vehicle adhesive that other manufacturers sell for this purpose. I.e bmw and Audi dealers will sell you the glue kit to fit their spoilers at the parts counter. Those glues are designed to stick abs plastic/carbon to paint.

I’ve used them in the past with the kit from bmw and they basically become one with the panel you attach them to lol. Want to remove it after? Probably easier to replace the panel.

The tape supplied was along the outside edge and was clearly inferior to the 3M tape, water got under it and it peeled off easily. I put the The 3M tape in the centre along the length and I think it covered the holes but can't be 100%. The amount/volume of water that got inside the spoiler was astonishing and (3m tape aside) has convinced me that one way or another I have to find some was of waterproofing that top front edge. Silicone sealant would do it but I feel like that's a bit brutal and I am looking for alternative options.

On the question of 'glue' raised here, again I reluctant to do anything that can't be undone because if I don't 100% right it would be a nightmare trying to get it off.

I will try it again with the 3M tape making sure to have it all well prepared and using a hair dryer to get a better bond. That just leaves me with coming up with a solution to the lip on the front edge and water getting in/

Just a thought - but you might be better off ensuring there is a small gap in the tape at the bottom to let water out, rather than trying to ensure it's completely watertight. In theory, 3M VHB exterior tape should be impervious when it's stuck properly, but in reality with it being such a complicated surface, it might be better to assume some water will find it's way in..?

I left a gap in the middle at the bottom where it's out of sight, and after heavy rain or a drive in the wet there is definitely water getting in at the top, but escaping at the bottom.

I think I posted this a while ago but I used the tape supplied with the Greendrive spoiler and put a bead of black silicone along the front/top edge to hide the gap. Left the bottom edge just with the tape holding it. Car is kept outside and it's still stuck fine after 2000 miles and a couple of months.

I've fitted mine, been a few weeks and seems well fit/stuck. Have you any photos of what you've done with the silicone?

This is it with the silicone... not sure if it's particularly visible or not though:

I too would be reluctant to use something permanent that might leave damage if removed.

I look forward to hearing how you get on. Best of luck!

Can't really see the silicone, that in itself is good, was looking for a close up photo of the ends, but I can sort of see what you've done if I zoom in (thanks!). I've just checked my spoiler instalment this morning again and it still looks and feels solid, its been raining off and on so its holding up well from what I can see. Glad I went with Greendrive in the end as didn't want to faff around with removing low quality tape off another branded spoiler and then installing my own at additional cost and time.

lol, this pic should help a bit:

Just installed my Spoiler, and wanted to give a run down to anyone attemping the same!
I purchased the Matt-Black Spoiler from Yikun Car Accessories Store on Ali-Express - Total came to $65/£52 with Shipping
Ordered on the 23rd of April and the Spoiler arrived on the 11th of May. So around 3 weeks delivery with the cheapest delivery option.

The package was 'Average' very similar to the other photo in this thread, however it was wrapped in Bubble Wrap and arrived with no damage. Included was the Spoiler with 3M Tape applied, and some 'Adhesion Promoter' Wipes (Which were Alchol Wipes)

I applied the Spoiler using the included tape, after deep cleaning the car and application area; however within 24 hours it was already lifting off the car at both ends. I also was unable to get the rear/underside of the spoiler to attach correctly to the car as the top side was so darn sticky it gripped the boot of the car hard and fast.

I then ordered a bottle of 3M Prime 94 10ML & 3M VHB 5952 10mm x 3 Meters.

Taking the spoiler off was worringly easy, however removing the existing tape was the biggest pain, I found the best method to be using a cotton bud and rolling up and off the tape, leaving the least residue. And a quick clean up of any left over gunk with some Isoproal Alchol

I re applied the tape and used the extra 20cm to reinforce the middle section of the spoiler.

On application, I only removed the tape from the bottom section of the spoiler, and left a little tuft of tape from the side corner for the tape on the top. This allowed me to get the spoiler in the right position, and to make sure that the bottom stuck!

5 Minutes of clamping it to the car, I removed the tape from the top, being careful not to tear it and then got my bottle of Primer 94 (which effectivly seems to be Super-Glue). I dribbled it under the top of the spoiler around the edges where it's known to lift, and then clamped it hard for another 5 minutes.

Initial opinions, the Primer 94 seems to do a hell of a job in promoting the adhesion of the tape; I'll report back if there's any issues over time.

TLDR: Don't use the Supplied tape. Grab a bottle of Primer 94 & Remove the bottom tape first, before doing the top.

Oh, and here's the final product;
