Product review (4 stars): I'd recommend it if you need to fix your racks but ...
Ordered this to try to prolong the usefulness of my dishwasher racks instead of replacing them. The lower rack especially had many rust spots. I applied about three coasts of the liquid cover and it's lasting very well. I also covered all of the prongs with the tips as many of them were showing rust as well. None have come off, and the liquid cover hasn't washed off either. I'd recommend it if you need to fix your racks but don't want to replace them.
