yes....John is right.....its hard to figure something to use for the inner and outter tub areas that will withstand constant banging/scraping along those areas, nothing is exactly fool proof.....
we just have to try and use stuff to minimize the future damage......
not a complete forever fix, but usng the FlexSeal on the outter tub gives a layer of cushion, and was thinking along the lines of a piece of rubber wrap, like an innertube glued to the top area of the inner tub.....again, over time both will sustain some damage from banging/scraping, but every bit of cushion will help some....
always was suprised GE never put in some layer of protection, one way or another, either a coating/shield for one of the tubs, or a suspension retainer that would not allow the inner tub to swing that far out to make contact with the outter tub...
as usual its up to us to think of things outside the box....
