V-berth with new teak paneling and bead board hull sides replacing awful old hull liner. New custom made end panel with front hatch opening to forward locker.

That looks great. Bought some vinyl bead board to line the hull of our O'Day 26. Also bought some glue used in a caulking gun and suitable for pvy and fiberglass installation.
Could you please tell me how you attached the bead board to the hull and if you found it necessary to apply the bead board with a small gap for expansion? Also, what sort of pattern did you use when applying glue to the bead board? Usually glue on a panel is applied from one end to the other using a continuous 's' pattern the length. Finally, have you noticed any expansion/contraction issues. Thanks for your help.
