Product review (5 stars): Good Stuff
I bought house with a ten year old Whirlpool dishwasher that had a severely rusted bottom tray.  I removed the rust with a rotary tool, applied three coats of ReRack on the grinded areas, and the tray looks new.  The thick consistency also filled in the areas that were thinned by grinding.  I can wait a few more months before buying a new dishwasher.

Update 7/27/2013
Rust has appeared on the repaired areas.  The repair lasted about three months.
