Product review (4 stars): I begin by saying that my dishwasher racks were HORRIBLY rusty (came with the house I bought)
I begin by saying that my dishwasher racks were HORRIBLY rusty (came with the house I bought).  I found the goop very hard to use ... too thick and dried faster than I could get it brushed on.  I used acetone to thin it a couple of times.  But I was able to get most of the rust covered, giving me a few more months out of my dishwasher.  This product would be most beneficial in the earlier stages of rusting!  The covers for the rusted prongs were very helpful and look great.
