Amazon After market Spoiler Install

[PhinFL]

As promised, here is my MS with the spoiler for JC Motorsport installed. It went on very easily and is locked down tight. Just went through a torrential south Florida tropical downpour (talking inches of rain in less than an hour) and the water completely wicked away down the sides or over the top. No water seepage underneath the spoiler.

I have installed this spoiler as well. A few pictures are attached. This is also just after a detailing by Clay at Before and After in Raleigh, NC (link). I would highly recommended if you are in the Raleigh/Durham NC area. He also applied Opticoat to my car.

This spoiler does have the issue where the left side does not fit snug on the body of the car. It is about 1mm off after attaching with the 3M tape. When attaching the spoiler, I held it down firm for 1min+, then weighed it down overnight. But as soon as the weight came off, it bounced back up and has slowly come up a bit more since then. The non-attached part is only the left-most ~3 inches. Suggestions on what to do? I noted someone up-thread suggested caulk...?? If so, what kind? The slight lift is barely noticeable unless you are really up close. So the only concern is getting water underneath.

PhinFL and Tomp:
Did you guys use the adhesion promoter in your installation of the spoiler? If so, what was the process you followed using it?

I used extra tape (see my previous post) to add some extra bonding power to the edges to avoid the gap that some are experiencing. In those places that I added extra tape, I used the adhesion promotor ONLY on the underside of the spoiler. I did not use any on the body of the car itself. Given time to let it dry completely before applying the new tape, and letting everything completely cure in the sun, I have had zero "bleeding" of the promotor.

I did not.

I did not use the adhesion promoter either. I too have the issue with the left side of the spoiler. Almost seems like there is a slight warp in the spoiler. It does not ruin the look but like others I am concerned about water seepage. Any suggestions on firmly securing the left side would be greatly appreciated. I read earlier the suggestion of silicone caulk but seem to remember someone saying that was a bad idea. Even with the little gap the spoiler really adds to the look of the car and I am glad I got it (especially at $153 shipped:biggrin.

I will eventually remove mine and replace with extra tape on that left side. PhinFL reported that helped fix his, so I'll probably do that, unless I can get clear info on auto-paint-safe caulk.

I used clear silicone caulking recommended by T sports line and my C Quartz Finest installer. It can be removed easily without ruining the paint.

Any particular brand suggested by your Cquartz installer? If so where did you get it? Thanks!

I bought a small tube of GE 100 percent all purpose silicone rubber. Does the job keeping the corners down and is easily removed if needed.

[tomp]

Thanks. So basically you mean regular silicone caulk? Like as sold at home improvement stores?

yes.

Has anyone tried using a heat gun to warm/heat the spoiler and bend the left side slightly so it conforms better to the trunk lip? I am making an assumption that the spoiler may be made out of plastic instead of carbon fiber.

Have anyone removed the 3M tape completely and only used some kind of silicone caulk or some kind of glue? I would think the spoiler would sit better and be a lot easier to mount?

 

[Iwan]

Hi guys, I bought mine just after OP's post. But didn't have time (or courage [emoji6]) to put in on.
Yesterday decided to give it a try.

I followed these instructions;
No glue, extra 3M tape inbetween the existing tape and most importantly, little extra tape in gaps around the edges for more retention.

This is my result:

Hope this gives some extra motivation to mount it [emoji16].

IWAN:
That looks like a really nice installation job you did. Did the outer edges lay flat in your installation?
Being in the Netherlands (where you get considerable rainfall at times), you will be best to report if water collects under the spoiler and eventually dribbles out once the car is dry.
Every car I have had a spoiler on did this, especially after I washed the car.
Then learned a trick to use a leaf blower or exhaust from a vacuun to blow out the residue water...

I got ticked, cut mine in 1/2. It's fiberglass. FYI

 

[Iwan]

@ArtInCT, fitment wasn't 100% flush, but with the extra pieces of 3M Tape, I managed to align it pretty well. After 1 night of rain still flush and no water dribbles.

I'll keep you updated!

 

[Iwan]

Update: spoiler is still flush and no water leaking.

 

[ArtInCT]

Very Nice. Thanks for the Update. Iwan.
