Product review (4 stars): It works
Great for touching up those rusted spots in the dishwasher rack. Easy to apply and it dries quickly. Several caveats:

1. If your rack is ready to fail structurally, don't waste your money on this, as it won't help. This is for cosmetic repair and to help prevent further rusting only. It also helps prevent the rusted metal from scratching dishware and glasses, but will not salvage a structurally unsound dishwasher rack. Only a new rack will fix that problem!

2. Thoroughly clean the places where you are going to use this with alcohol or other such material to clean off all soap and residue. Try to get all loose rust out of the area and be sure it's COMPLETELY dry before brushing on the Plasti-Dip.

3. Place a folded paper towel below and between the pegs of the rack and anywhere you don't want this liquid vinyl to adhere or drip on.

4. Give the area multiple coats and allow the material to dry THOROUGHLY between coats.

I know this repeats much of what is already on the instructions, but if the area is not super clean and dry, the coating will simply fall off. Also, be prepared to do the job again in the near future. Sadly, once things begin to rust, stopping the rust cycle is almost impossible in that moist environment, and the rust will continue, albeit more slowly, under the new coating. I've had the dishwasher rack last several more years now by cleaning and recoating as needed, so if you do the same, hopefully you'll have good results.
