This morning I did some roof panels before we went to Thrill Seeker to do some things before it goes to the water. This time I glue the panels with PU construction clue, I think this is faster because I don't have to fill the seams. The panels are 61 cm wide. I also ordered some 15mm for the panels where the windows will come. I don't want the windows on top of the outside but sunk in it.
