Product review (5 stars): Money Saver
This stuff is awesome.  It revived my dishwasher and took away the need to replace it because of rust stains being left on my plates and glasses.  Do read the directions on application.  Make sure you are in a ventilated room as the smell is quite strong.  I used it on both the bottom and top racks and it required 2 bottles to get the job done.  By the time I got to the bottom of the bottle it was getting thick.  It has been a few months now and the repairs are still holding strong.  I put multiple layers on letting each layer dry before adding the next.
