Product review (5 stars): Dish Washer repair
As soon as rust appears, repair you dish washer rack. I waited too long and had to make some adjustments.  This product worked very well.  I used the tips on ends that resulted from a rusted through area.  The liquid covers and looks good as long as you have cleaned away the rusted areas. If you dab the liquid on it looks better that painting it.  If you do one side at a time and apply more than one coat, it makes a nice repair. New racks are expensive so watch for rust and use this product.
