Hi Ulf. Indeed. First I tried the talcum powder, but that stuff did migrate into the seams.....took some time to clean up. After that, I used a slip sheet using 3M masking film. I do not think that that film is much more than a mil thick. The film really helped in keeping the back side of the seat cover from sticking/binding to the foam forms. It did make the job much easier, and I wound up with fewer wrinkles. The wrinkles, which I had, surprisingly, stretched themselves out a few days after the installation was complete. Like they say, walk away for a few days, and it will look better. Thanks for following. sgrip65
