amg deck spoiler from jbspeed
i just purchased anamg rear deck spoiler from jbspeed. it looks great. i just wanted to know if anyone has experience in installing it. looks pretty simple (it comes with double sided tape). is there something i should do to the paint, besides washing it, to allow the spoiler to adhere better? any recommendations would be appreciated. thanks.

I have the same decklid spoiler. Great piece. Very strong recommendation for adding a bead of urethane the full length of the spoiler (MB makes a urethane product in a squeeze tube), taping the spoiler down, and keeping it still for several hours...no driving...so there is no flex while it cures. There have been a few reports on even well-applied tape coming loose. The spoiler will be very difficult to remove, if you ever want to do so, but it can be done. Meanwhile, think of the people in the car behind you on the highway.

Whatever the "homie" did, he did it incorrectly. Urethane is not inherently damaging, just more challenging to remove, and it can be done without damaging paint if someone knows what they are doing. In any event, the lives of someone behind you in traffic trump any concern about a paint repair. The spoiler is just about the right height to penetrate a following windshield. If you're not prepared to understand that, don't put the spoiler on your car.

When I first purchased my CF trunk spoiler from JBSpeed, I thought I'll just put it on with the tape they equipped it with. I remember you saying to put urethane but I thought this should be fine. Now it's been about 8 months since I've had it on and I noticed that it started getting loose. Not loose around the corners but towards the middle. It doesn't look like it's holding on good and I probably will be taking it off and putting the urethane which I probably should have done. I don't know why I didn't put it on the first place but I sure will do it now. Can you tell me where I can purchase it?

I learned about the tape being no good the hard way. I tried using tape only on my roof spoiler and it flew off on the highway. Thank goodness it was 1am and nobody was on the road behind me. This will never happen to me again.

I think 3M doubleside adhesive tape holds spoiler strong enough. I tried to pull it doesn't even move. Maybe because I have put extra tape on the spoiler. It's all good. I like it. They are great.

I wish I could, but I've learned to rely on the experts at MotorWerks in Commerce, Michigan. They taught me about this issue, and showed me the process when they did my car. The urethane they used is a Mercedes Benz product and comes in a squeeze tube, like toothpaste, but black. I think my first stop would either be an auto supply store for comparable products, or go the MB dealer parts department. I don't see this category of products on a MB parts website I just checked.

Man, I wish I wasn't so impatient with my spoiler.
I put it on without any extra tape or adhesive. I just wiped down my trunk lid, and put it on. I even noticed it didn't stick perfectly all the way around (some parts just didn't flex enough to get a true grab on the trunk). I immediately drove it afterward, then noticed when I got to my destination, that the middle part closest to the rear window wasn't sticking. I literally sat on that area (with my arms), and each area of the spoiler aside from it for like 5 minutes, and it was/is nice and stuck on.
It seems to be stuck on well (the spoiler), but I could have taken the extra steps. I even get worried when the car gets wet, as I'm afraid there might be tiny areas where the water can seep through.

I ordered mine from JBSpeed also, but I had the body shop at the dealership put it on for me. That way if anything happens, it falls back on them.

3M Double Sided Automotive is secure enough as long as you apply it properly. Surface needs to be properly prepped by removing all contaminants and LSP. Clay the surface, then do an IPA wipedown. Same goes for the underside of the spoiler. I apply my own tape as I'm not sure how properly prepped the underside of the spoiler was coming out of the factory. Heat up the adhesive with a hair dryer or heat gun prior to application and make sure the surface of the car is warm/hot to touch. Apply the spoiler taped down from one side to the other to prevent any arches or air pockets. Then tape it down tight and slight downward pressure (books or weights work great) and allow to sit in sun on warm day for a few hours to let the adhesive properly cure. This is the step several shops won't do cause they don't want the car/customer sitting there for a few hours, but is a good step to enforce.
