Product review (5 stars): My Dishwasher Looks Like New
This stuff is great. I was pricing new dishwasher racks (expensive) to replace my rusted ones when I ran across this product.  I couldn't pass it up for the price; I figured it was worth a shot and it was.  It takes three to four coats to do a good job, but the time involved is worth it.  No more rust spots on my dishes. No more rust spots on the interior of my dishwasher. One bottle is more than enough to do one dish washer.  Don't buy new racks; buy ReRack instead.
