I need some advice with resecuring my bow rail. I know there is alot of moisture where it is screwed to the deck. Heard one idea, to drill with a 2 inch holesaw, through the deck and put a layer of glass underneath. Then add structural filler to the 2 inch hole. This would give fresh meat to screw into and be able to get rid of the balsa that is wet and rotted. Also to drill 1/2 inch holes to see how far the saturation is and then take balsa out. Then use west system with a caulk gun to fill. I want to do it right and be done with it. any advice would help.
