How was fitment on your 3DCarbon rear spoiler?

[Mike_ZN6]

I have been having some issues getting a 3DCarbon spoiler installed on my car. I have had 2 of these spoilers now. About 2 weeks after I got the first one installed, both ends of the spoiler lifted up. I ended up getting a second one and had it installed at a different shop. When I went to pick it up the spoiler was already lifting up in some spots!

How difficult is it to get 3M tape to hold one of these things down? Everything I read says it should be easily strong enough to permanently attach a spoiler. But after going to 2 different body shops and having the tape lift up, I am at a loss.

One thing that comes immediately to mind. The 3M tape is bonding to the paint, not the trunk lid. If the paint is defective (lifts easily) then the tape isn't going to hold. Is it the tape separating cleanly from either the spoiler or the lid, or is it the paint separating from the car/spoiler with the tape?

If the tape is separating cleanly, then the area probably wasn't prepped correctly. It doesn't have to be perfect, but it does have to be done per the instructions.

If it's the paint that's lifting with the tape, then there's your problem.

(Not saying it is, it's just that came to mind when reading this)

It does not appear the paint is coming off the trunk and sticking to the tape.

It looks like in some spots the tape is seperating from the spoiler and staying attached to the trunk. In other spots, it seems the tape is staying attached to the spoiler but lifting off the trunk.

The ends of mine are lifting after 14 months. Might have to reinstall. Maybe use heat gun to bend the ends in the opposite direction before reinstalling.



IMO the best-looking lip/spoiler for the twins...

Remove the spoiler and clean the areas where the 3m tape makes contact.
Before applying it again use this.

I've used this before and it definitely helps. Now if the spoiler is warped bad enough that's another story but that adhesion promoter is cheap enough to give a shot.

are you sure it's genuine 3m tape?

if in doubt, replace the tape with some store-bought real stuff

The most recent shop told me they use genuine 3m products, but I am not 100% sure.

The installer said they used the 3m adhesion promoter. I got in contact with 3DCarbon and they think the problem may be that both shops did not leave a small gap between the tape on the ends of the spoiler and the tape running along the middle parts.

I am going to reinstall soon and hopefully it stays this time.

Agreed! I kind of don't like the look of the car without it!

I suspect these were manufactured a long time ago, and where you find "new" items for sale, they are leftover stock. May be best to replace all tape with new 3M in addition to a meticulous prep.

[Mike_ZN6]

Does anyone know are you supposed to use the 3m adhesive promoter on the spoiler before you apply the tape to it? Or just use it on the trunk?

Did you purchase the spoiler unpainted and the body shop painted it? If yes, did they also paint the areas where the tape was to be applied on the spoiler? If they did that could be your problem. Those areas are supposed to be masked off before painting. Installation instructions: http://toyotaparts.sparkstoyota.com/...-61042inst.pdf Scroll down to page 14 of the installation instructions. FIVE:AD was purchased by 3DCarbon.
I purchased a pre-painted FIVE:AD rear spoiler back in 2015. The 3M tape was pre-applied to the spoiler and it came with 3 tubes of 3M adhesive promoter.
Followed the installation instructions and it looks as good as the day I installed it. The ends have not lifted.

Does this 3DCarbon spoiler cover up all of the holes from the OEM FRS spoiler??
