Product review (4 stars): Worked great
I bought this kit to repair rusty diswasher rack prongs.
It worked great.  The color is perfect for my Kitchen Aid dishwasher rack, which began rusting after 2 years.
After replacing/repairing all of the rusty prongs on my dishwasher, I gave the repair kit to my parents who repaired theirs as well.
The only drawback is that it emits quite a strong odor, so I would highly recommend doing the repairs outdoors.
