Product review (5 stars): Worked great, but strong smell
Delivered quickly and worked really well.  We had a lot of rust areas on our dishwasher racks.  I didn't put on as many coats as I wanted to, but even in the areas where there were only one or two coats, it's held up so far (5 or 6 weeks).  I would definitely recommend using this as soon as any rust areas show up as the earlier you coat them, the better.  The only negative was the strong chemical smell.  It didn't bother me, but gave my wife a bad headache.  Other than that, I have no complaints.
