Ive been stretching the headliner for 3 days a little at a time with the binder clips on all sides. The center bow at the ends have v- shaped wrinkles coming down towards the window opening and I cant seem to smooth them out and the area just above where the sail panels looks a bit loose as well. Any suggestion on how to make these areas look better before I glue this thing, Its pretty much trimmed all the way around and the front half from the center bow looks good, the back half on the sides looks terrible. Any thoughts or suggestions?

Thanks Rich

I had some similar concerns , here are some fixes ..........

I started the process at the rear view mirror.
Snap all the bows in place.
Pull mat'l tight at the mirror and continue pulling tight to the corners of the front w/s.
Go to the rear qtr window, sail panel end is good, and pull tight.
Go back to the front w/s and start attaching the h/liner to the middle of the side. Do a couple inches on one side, then swap sides.
Start at the rear window middle and pull tight.
Pull the bottom of the sail panel tight.
Attach rear window h/liner.
Now go back to the sides and continue attaching.
Pull and attach.

I did this and wore the hell out of my thumbs pulling and attaching to the strip. I did not glue the sides and ended up with a wrinkle on drvr side of the rear window in the top corner. I sort of ran out of patience by then, the last corner.

You did leave the h/liner in the sun for a day or so? It really helps in smoothing out the wrinkles and makes it more pliable.

Good luck.
