getting the damn roof spoiler to stay!...arrgh

[martini]

so i had my roof spoiler on for a while, but as the weather heated up it seperated from the window.

I used 3M double sided tape and it didnt stay. I was looking to see what other people have used.

I think an epoxy would work, but my roof spoiler doesnt lay flat naturally on the window... there is some flex in it, so it needs to be pushed and held on the window so it doesnt bow up. That is why the double sided tape was so nice - I didnt have to wait for it to cure, it just stuck immediately and made the spoiler fit perfectly.

I am wondering if I needed to clean the window with something else before I put it on....


any suggestions?

Before, I installed my trunk spoiler, I cleaned the area with goo-gone. But if this is getting attatched to a window, I would clean it up with some acetone, or a bleach of some sort.

Either way, I am surprised, I never thought roof spoilers with held on by adhesive!

rubbing alcohol should do the trick

any other suggestions?

How about 3M tape on the corners and then epoxy as well? The 3M will hold it down so there is no flex while the epoxy cures. When the tape wears out there will be epoxy to hold it.

Yeah, I was gonna suggest a few strips of double sided tape along with the epoxy.

i just got a rppf spoiler myself ...i got it installed by the guy who painted for me ....i asked him what he used just in case i want to remove it and he said he used some kind of window silicone ....so far its very strong but im goin for a car wash in a day or two so thats going to give it the ultimate test

You need adhesion promoter pads made by 3M and some prepsolve for cleaning the area you're going to work with. You can find these at a bodyshop product store.

cleaned window with rubbing alcohol.. 3 strips of double sided tape.. let sit in sun to get soft.. put weight on the middle because it was not touching window.. took it into the garage overnight.. was fine the next day...

I watched mine get installed after it was painted and the guy ised a silicone adhesive that was black in color. they put some presure on it for a little while then taped it down and told me to take the tape off after 24 hours. Mine stays down perfectly.

If you can't get it to stick by this weekend, get in touch with me at Waterfest and I'll direct you to my guy that put it on, he works all hours of the night usually

That's what my guy that installed mine used. It rained the day after I got it installed and nothing happened

I also used sikaflex as thats what came with my BMW roof spoiler. BMW also carries a urethane adhesive in their parts deprtment thats available if u cant find sikaflex. I used the glue with the 3m tape to hold it in place and on 3 different cars they are solidly in place. I tried just 3m tape only way back when and when winter came the temperature caused the spoiler to just fall off.

I tried the doube side 3M tape, shit sucked. Ended up using 3M black marine silicone. Had to take it off to get me rear window retinted, took me an hour to get it off, that stuff definitely works and works WELL!

[dirtyserby]

what about the betalink stuff from bmw???

[jcg05c]

Michelle and chris(bwoy) both used poxy, looked good to me.

why the hell did u have to take it off to get your window tinted? Tint goes on the inside of the car not outside.

[davidlizard]

double face 3M for immediate and windshield urethane for long term... as a spoiler!!!

to cut the tint to the shape of the window

[a2gtinut]

Betalink works great.
BMW uses that on everything.
