Product review (5 stars): so good as for staying on
These really helped cover the rusting tips of the dishwasher rack.  I hope to get another couple years out of the machine and I think this will do the trick. So far, so good as for staying on. Can't beat the price for this "repair" vs buying new racks.
6 month Update...still good!  Best $10 I have spent!
UPDATE!
Still holding on over a year now!
