Product review (4 stars): but so far (2 weeks) works fine, covered the small rust spots and the tips ...
Product arrived quickly. Works as instructed. Is very "goopy' not sure it could be any smoother to brush on, but so far (2 weeks) works fine, covered the small rust spots and the tips are still attached.  Would buy more if any other spots appear. Dishwasher is 25 years old, works fine and I don't need to buy new racks now.
