Product review (5 stars): Range porcelain cooktop
works great on dishwasher racks. prep is key. those who say it didn't work likely had poor prep. note those that mentioned the meticulous prep and still good after 3 years. I used it on a chipped corner of my range cooktop, not perfect but looks better than that ugly black metal on my white cook top. I see it but no one else does. take your time, and spend an afternoon (in a ventilated area) watch a game, but don't get too excited or you may knock over the rack before its cured. like any good paint job, prep is key.
