Product review (3 stars): Quick fix, but not forever.
My dishwasher rack was starting to rust near the bottom and at the top spindles. The results of this product was mixed. The caps work great! They adhere quickly and are long-lasting.  My dishes are no longer scratched.  At the bottom where I just applied the paint, I had not so great results.  Over time, the dishes that I put in the rack wear off the paint.
