Product review (5 stars): An easy fix for rusty dishwasher racks.
The seller delivered the product on time and even e-mailed instructions.

Be sure to scrape or sand all the rust off first and remove the plastic coating over the rusty area. I suggest using naval jelly rust remover or rust reformer to treat the rusty area. Pour some acetone (available from hardware stores) in a small jar. Dip the brush that comes with the paint in the acetone once in a while and wipe with a paper towel. This will remove the gummy deposit that will form on the brush and its stem as the paint dries very quickly. Although the paint dries very quickly, you will have time to treat at least two areas before dipping again in the paint bottle. Be sure to cover the  opening with your thumb, as suggested, to keep the paint from drying out in the bottle.

The light gray was a good match for my dishwasher. I applied two coats per instructions and will update this review in a few months to let users know how well the paint lasts.
