Product review (3 stars): Thick and goopy I gave up the dishwasher rack use and used it on my in-sink dish drainer.
Goopy and similar to very old, very thick nail polish, I realized it would require 2 coats to cover the tines of my dishwasher rack.  After reading you must "remove rust from the tines of the rack before coating" I decided it required too much labor and decided not to chance it. (Need to find a spray version or a larger bottle of liquid coating!)  Instead I used it to cover the in-sink metal dish drainer feet to prevent them from rusting and scratching my sink. (My initial idea was to coat the bottom of the in-sink rack to form a thin cushion but there was not nearly enough to accomplish this.)
