Product review (3 stars): Wait and see...
I touched up my dishwasher about 2 weeks ago--not yet long enough to see if the rust pops through. I was happy about the packet of rubber tips to put on exposed ends, but they were too small for my racks, especially after applying some of the paint. I managed to squeeze some of them on and added more paint to secure them. I was glad I read others' comments about keeping the cap on as much as possible (the paint on the brush and neck of the bottle tend to get dry and goopy) and to apply the paint in a ventilated area (the odor is quite strong if you breathe close to the bottle).
