The first task is to block all the holes on the floor which were to secure the seats, anchor points, wheelchair lifter and securing the plywood.
I used a roof flashing tape which it is all-weather and waterproof.
Each hole was cleaned and plugged. Later on, I would paint the chassis and the bottom of the floor with thick chassis paint to seal any hole and also reduce the road noise
Tomorrow we start with the insulation and preparation for fitting the 9mm marine plywood.
