John,
Thanks for the comeback. The tanks are corroded on the bottom side corner and lower side wall. Each tank is pitted right through and crumbles to dust when I touch or brush my finger over the corroded area(s)
. The builder put the tank flat in a coffin box with 2 part foam. Saltwater got into the area and it was sealed so air flow was severely restricted if at all. Funny how that works because if it was sealed then the water wouldn't have gotten in to begin with [img]/forum/images/graemlins/tongue.gif[/img]. The tanks have to be built to the same spec as I don't want to modify the floor line. Let me know what your friend comes up with re: finding a tank builder on the West Coast. Thanks, Greg
