Product review (5 stars): Works as it should when used correctly
I have been using ReRack on dishwashers that I repair and resell for a number of years now.  The key to making this product work properly is to follow the instructions, and, as another poster said, it will not help a rack that is rusted completely through or almost all the way through. Also, only apply the product to a DRY rack, as painting it over a damp rusty spot will only serve to trap moisture under the coating, which will result in continued rusting of the rack beneath the coating. Also, make sure that it is fully dry and cured before running the machine. I always try to file or sand away as much of the surface rust as possible before application, but I have received dishwashers that the previous owner repaired with ReRack without any surface prep. A few had rusted so badly on the tips of the tines that after the owner covered them with ReRack, they resembled Q Tip ends, but the repairs held up anyway. Great product when used properly.
