Product review (4 stars): It worked
Almost all of the tips had worn off the racks in my dishwasher.  This was causing rust spots on my dishes where the rusty tines were touching the dishes.  Needed a cheap fix for this problem.  Enough tips were included to cover both top and bottom racks.  I started by sanding off the rusty spots with a dremmel.  (Be careful when sanding that you don't take off too much of the vinyl covering.  The vinyl touchup works but is very, very thin.) Tips worked great and have held in place.  Covered the bare spots on the racks with the vinyl touchup.  Seemed to work, but the product was so thin I applied several coats over several hours before I was satisfied with the coating.  Still wish it was thicker, but it is holding just fine.  Now my new dishes aren't getting rusty spots.  This was a much cheaper fix than replacing the racks or buying a new dishwasher.  Fast shipping.  Pleased with the product.
