When you guys installed this, it mounts on the rear window seal correct?

Also, the ACS one came with a bunch of stuff such as cleaner, sand paper, primer, adhesive, etc...Damn do I use all that stuff?

 

I mounted mine just below the seal so that it only touched the window and not right on the seal. Mine only came with double sided tape.

 

you got the real thing because my did not come with the cleaner, sand paper, primer, adhesive, etc
I installed my after the seal too.

 

It looks like there is a groove or channel on the top and sides of the roof spoiler. My guess is that this goes over the window seal. So do you guys put the adhesive on the glass itself? What kind of double sided tape did you use and where do I get it?

I used 3M tape. I put it two layers on the spoiler, then glued it onto the window and put some weight on it for couple of hours.
I also heated the tape with a regular hair drier before I pushed it on to the window. I used two layers, because my plastic replica spoiler tend to pop up from the both ends, because it is just a bit less curvier than the window itself. With two layers of tape I got more elasticity into the attachment and now it's been there for 1 and ½ years through the winters and everything.

Where can I get the double-sided 3M tape? I think I'll go this route. Mine seem to match the curvature of the windshield pretty good.
