Because the windows sandwich headliner on the interior of the boat I had to get that glued in before I put the windows back in… and I needed the windows back in so the boat was weatherproof before winter. I was extremely nervous gluing the headliner back in. It goes on with contact cement so you get one shot to get it right or else you have to tear it out and wire brush the foam off and clean it all with acetone again before the next shot. Help from Lorena and Ryan made this an easy job with no mistakes. It turned out great.
