Product review (5 stars): Make that nasty rack new again!!
I didn't buy mine from Amazon, but instead I found it at local hardware store. However, I think it deserves a 5 star review here. Like many of us with older appliances, my lower rack was starting to show age, but not enough to replace the unit and not enough to warrent a $75 or more new rack. So I thought I would give this a try. Glad I did!! Just make sure you wire brush or light sand the exposed/rusting tips and rails. then wipe clean with rubbing alcohol. Shake the bottle and start brushing. I did find this little trick handy. If your tips need it the most, simply hold the bottle upright in one hand and tip by tip, just dip them into the bottle enough to coat. Let the excess run back into the bottle. (Much like regular plastidip).
Let it all dry really well, then into the dishwasher for test run. Mine look great and I had a couple really bad spots to fix, which required me to do several applications of this liquid plastic.
