I have a rear window deflector that i can't get to stay on. It came with the 3M double sided tape and it wouldn't stay down. So i removed it put new 3M tape and doubled it up where it wouldn't stay down, and it still kept coming off. I can't find anything that will hold it down without coming off. What would be someting good to use?

 

Remove it and leave it off.

 

I'm going to go out on a limb here and guess that you didn't prep your surfaces correctly before sticking it on. Wash your car, then use Dawn, or some other cleaning fluid that will cut through grease, grime, bugs, bird ****, and wax. Do that on the car, as well as the wing. You "doubled it up"? Do you mean you stacked it, or ran two lines side by side?

 

Alcohol prep pad on window then pressure when you put it on. Let it sit a day to adhere well.

 

... And use 3M adhesion promotor on both the deflector and on the surface you are sticking it to.

 

Why does a street car need a window deflector?

 

So when vtec pops he can fly.....duh...he should probably get some street glow so he can light up the road at night...kinda like landing lights

 

"ARROWdynamics". hahah

 

one of those aero parts that have no areo properties on a street car
