I have a great X-2 that is in real nice shape. I noticed that the thru-hull fitting on the back of the ski where the trim comes out was not attached. It was aout 1/2 inch out. What do I use to seal up the brass fitting to the fiber-glass. 3m 5200? Will this be strong enough? The brass fitting that fits in the fiber-glass will have to adhere to something since the out side edge is gone. The fitting pattern is fin and the brass fitting slides in with a little help. What should I use to hold it in place tight and to make a waterptoof seal. Thanks, J
