Hi Jorgen, You are absolutely correct regarding dry time for the adhesive. I think the adhesive recommends 3 or 4 minutes. I did this job 5 or 6 years ago, so I cannot remember the correct time.? Do not jump the gun and do it sooner than the recommended dry time or you will get bubbles (again, don't ask me how I know). Also use a rubber roller to smooth out the Naugahyde after you apply it. When you wrap around the long edge, use stainless steel staples to hold the Naugahyde in place. On the short edges, trim the Naugahyde about an 1/8" longer than the edge of the board to allow for any contraction. My headliner came out great, in fact the guy who owns the yard wanted to know if he could pay me to do other boats. I said no way since it was a labor of love and took a good deal of time.? Good luck with your project.
