It only took a few hours to remove the hardware and old material and do the initial fit of the skin on the frame. Taking the advise of others about attaching the material to the top while the frame is in the unlock position I was able to secure the sides without to much trouble. A quick check of the top in the locked position revealed some ripples and it felt somewhat like a blister. It looked OK, but when you touched it was very soft and spongy. My solution to this was a beer break - while the top sat in the 85 degree sun for 20 minutes to soften up.
This is the way to go ! When I brought it in I could hardly touch it, but I was able to stretch the material a good inch and a half beyond where I had initially had it secured. When I snapped the frame to the lock position it gave a very reassuring POP and WOW was I impressed with myself !
The top looks great and I still get that great feeling of slaying another Porsche maintenance dragon. Now that you've read the book, now here are the pictures of this project.
