Quarter Window Adhesive Tape

[montegut]

I am having to replace my quarter windows, GT, and have the Fiero Store premium replacement. The windows are great quality but the supplied adhesive tape is giving me a problem. I bought the windows over 2 years ago when my car was damaged but had no idea it would be this long before I was able to replace the windows. The tape is just not holding. Don't know if it is just old. I followed all the directions on surface prep, application ect but after 24 hours, the windows came off quite easily. I just got back from O'Reilly's and bought the 3M heavy duty automotive trim tape but it is very thin. Any recommendations?

The trim tape is very thin.  Did the tape come loose or did the paint release from the window?  If it was the paint that released, they didn't print them with the propler ink. 

The proper tape is a double side foam tape. Per Paul McKibben's Fiero Sails website "The tape for fastback quarter windows is 1/2" wide x 3 mm thick (120 mils) Very High Bond (VHB) closed-cell white acrylic tape with adhesive on two sides. The 3M product number for a 36 yard roll is 4959. "

Edited:  In his info, he says that it comes in a 36 yard roll but you may be able to get shorter rolls at https://www.tapecase.com/search?keyword=3M%204949%20VHB%20Tape

Clicking on the tape says it's discontinued and directs you to a substitute #5952 VHB tape.   It might be possible to call Matt at The Fiero Store and ask if they can sell you some fresh tape since you got the windows from them.

The paint on the windows and car is fine. The tape pulled off easily from both the windows and car so I think it’s a problem with the adhesive just being old.
I will check with TFS tomorrow about just the tape. Thanks

I have also heard/read discussions about the tape. When Doug Kinney was running Fiero Warehouse, and selling those windows (Chris Cook's "cheaper" ones, I think) he said that the regular trim tape was too thin. He sourced - and recommended - an alternative. This was a long time ago. It may be the same stuff that Paul M recommended.

I was able to order the tape from  The Fiero Store. Hope to install the windows this weekend or next. Will post pictures if it goes well. If it goes poorly I can be found in a corner of my garage in a fetal position.

Make note of where the oem tape was placed.  Also leave several 1/4 inch gaps in the tape across the bottom for drainage.

Will do. Thanks
