Product review (4 stars): Works great - can be time consuming
Product works great, sealed off all the rough spots on our 10+ year old dishwasher rack.  Good solution since we plan to just get a new dishwasher in the next year or two, and didn't want to spend 150+ buying new racks.

We had quite a few bad spots, so I took a dremel to grind them down and then used the product.  Just took a little while.
