Product review (5 stars): This worked great! Our Bosch dishwasher rack tines were rusting
This worked great!  Our Bosch dishwasher rack tines were rusting.  One had even broken off.  I checked the price of new racks and we might as well look to buy a new dishwasher--well, not really, but they were pricey.  This product has the racks looking like new.  So far, we've washed a couple loads of dishes (after letting the product dry overnight just to be safe) and none of the tine caps have come off.

It's an epoxy and comes in a glass bottle.  I don't recommend dropping it on tile floor like my husband did, but it did get him to complete the project quickly when the bottle cracked.  And that section of kitchen flooring has never been cleaner.  lol.

Anyhoo, I highly recommend.  Looks great, matched the inside of our Bosch dishwasher very well--looks brand new.  Highly recommend.
