Product review (5 stars): Excellent product that does what it says!!
This stuff is excellent.  My dishwasher racks had several rust spots (10-15 to be exact) that were getting worse. The problem I had though was that my dishwasher rack was a darker gray color.  All I did though was mix in a small bit of regular black paint to turn this Rerack coating a perfect matching gray.  I've used my dishwasher a few months now without any issues - everything still looks great!
