Product review (5 stars): Worked exactly as advertized.
I lost the first set of dishwasher racks to rust and buying new one is VERY expensive.  I was lucky and found a used set of racks for a reasonable price.  They were basically unused.  Upon inspection, they were manufactured with many places that could rust in the future.  I used Uber Goop to coat the placed and installed end caps where there were none.  The Uber Goop worked well.  You must work fast, because it dried fast.

So far, after about 2 month it seems to be staying in place.  Sure beats RUST!
