GTS solarwing
 

Does anyone have one but more importantly does anyone have that the ends don't stay stuck to the window. I've redone it with new double sided tape one, and it stayed for some time but now it's resting against the body again...

i had one on my 88 gta and then put it on my 84 z28. never had any issues.
What brand tape are you using?
take all the old tape/adhesive off, clean the residue off the hatch and solarwing, clean it well with an alcohol based cleaner, then us 3M double sided Molding tape, it'll hold good then.

come on man there other tape then 3m... i always use 3m...cleaned and recleaned. Maybe my car is too fast...3m can't hold

the gray 3m molding tape wont hold?... somethings not right, lol. i've used that to hold gfx on.
even the wrap around wing on my gta was held on mostly by this stuff, haha.
