      i do my wrinkle at 350* for 25 minutes. they will wrinkle quicly then go to glossy, then back to wrinkle at about 15 minutes.
      Never argue with an idiot...they will bring you down to their level and beat you with experience.

        Didnt have any problem here. Looks great! Put parts in cold. Turned oven on to 400 degress... took about 12 minutes to get to temp/melting look. Then waited another 14 minutes. Let cool with the the door cracked open.

        Perfect!

            Could be how much powder is being applied to the part. Try a couple test panels at different thicknesses.

              The only time I've ever had problems with a wrinkle was b/c a blocking agent was being released by another powder I was running and it just killed the wrinkle... A good article on troubleshooting wrinkle finishes:
