Product review (2 stars): Didn't really work
I ordered this product first, then started to work on the rack. The question that is not answered is whether the product will stop the rust, or only cover it up. Because of this, I endeavored to remove the old enamel coating to expose the rusted areas. It was easy to find, as the rust expanded the coating. I used a file, scraper, needle-nose pliers and sandpaper to expose all the rust. Some areas were very thin when I had removed the loose rust and coating. I used wire to repair the rusted off sections. Then, I sprayed rustoleum ($5) for heavily rusted areas on the rust areas, then coated the areas with multiple coats of the ReRack. The single bottle went quite far, but I bought 2 so I had some left over. Total cost was $25 plus maybe 5 hours of scraping. A bit of work, but it will extend the life of my dishwasher.

After 2 years the rack is again covered with rust. I think Rerack did not stop the rust, only cover it up. I now just spray painted over the rust with white rustoleum several coats I hope this will work. In hindsight, the Rerack is good for the rubber like coating racks like to prevent scratching the dishes, but you need something like several heavy coats of rustoleum to stop the rust first.
