Product review (2 stars): Not as Good as I Thought!
I used the Plasti Dip product on my dishwasher rack.  I followed the instructions for the prep and application.  It only lasted about 8 months and rust is coming through the areas that I repaired.  Although it's not that expensive, the trouble it takes to prepare the surface is time consuming.  I think I'm going to order some new racks next time...
