Product review (5 stars): Dishwasher Rack Repair Kit
This is a great product!  I moved into my parents home and the dishwasher rack had several nickel size places where the rubber coating had worn through and the rack was rusting.  About a dozen of the prongs that you set the plates between had also worn off and rusted at the top.  I did have to cut some of the prongs off about a half inch before the little rubber tips would go onto them.  The brush on coating for the rusted spots took only two coats.  The rack looks like new and I am very pleased with the product.  I would recommend it to anyone!
