These are the scoops on my car that are glass mount and don't touch the paint. I'm sure there are plenty of louvers that mount the same way.

Roush side louvers here also.
I used the adhesive promoter on the brackets themselves and
the glass, but not the area where the tape was affixed to the body.
You are going to have clearcoat damage when you remove the louvers.
The edges of Roush Louvers contact the paint and there are telltale
signs of them being on there when removed.
You really have to commit yourself to Roush 1/4 window louvers.

I just got some louvers from RPI designs and maybe I was a little overzealous in my haste to install them. I washed my car, and then w/ clean windows, but w/o using any solvent such as rubbing alcohol, applied the louvers to the 1/4 window glass w/ the attached 3M tape (it was a clear type of tape as opposed to the sponge-like tape that came w/ my tail-light bezels). Shortly after the install I noticed the top and bottom of the front edge of the louver pulling away from the glass, now it seems that no matter how hard I push the louver back onto the glass, the tape keeps releasing, would it be possible to drip some adhesion promotor down there to help it stay stuck, or do I need to pull the louvers off completely and re-install w/ new tape?

Hopefully I didn't screw myself over here.

You need to redo them, even if the adhesion promoter worked, which I doubt it will, obviously the bond is going to be poor in other areas too.

Dammit, just what I didn't want to hear, but its no one's fault but my own. Where can one buy the 3M tape and adhesion promoter so that when I go to redo these things I can get it done right?

+1 on redo.

Most auto parts stores carry the tape, promoter and, if you're not using 90% or better alcohol, a good solvent.

The preparation is 90% of the install. Be sure that you tape-to-louver application is done right, too. It'd be a b*tch to have the tape-to-glass fine and then have the louvers pulling off from the tape. Be mindful of your temperature (above 65 deg. F if I recall) and cure time (24 hours of NON-MOVEMENT of the vehicle).

I took mine off this spring, but it took a lot of effort. I went to Lowes to get my tape, it's the Scotts 5lb black. I like the Scotts b/c it is wider then the stuff they sell at the auto parts stores. This is useful on the front part of the scoop where there is a larger contact spot with the window which takes the most force from the wind.

I have had mine on for two years and have not had a problem. I cleaned the surface with alcohol and then wipe the tape with promoter as instructed.

Ato,

What did you do/use to remove them from your car? Mine are off by a few degrees and it drives me crazy. I want to take them off and start over, how'd you get them off and get the tape off the louvers? Thanks.

Tape and fishing line. I sent you more details in a pm.
