Can you "fix" a bad top install?

I have done three tops in my past, not a professional. Each one better than the last. Yes, take it apart. Looks like he started at the front then worked back. All the manuals I have read state start at the rear window and work forward. Get a manual. Also looks like there might need some top adjustments. Make sure the frame is in good working order. Pulling the vinyl and stretching it is the only way to get the wrinkles out. They wont shrink in the sun. I have seen some people use a spring stapler on the rear bow/window. This will not hold up in the long term. You will need an air stapler with stainless staples. If not rust stains will run from the seam. Good luck and take your time. Your biggest drawback is you don't have extra material to have to work with, its been cut off.
