Product review (5 stars): Follow the directions and you can't go wrong, Great Product!
I used this product on my dishwasher racks about 3 weeks ago now. Seems to have worked very well. Now that the racks are repaired, you cant tell them from new unless you inspect up close. We had previously tried to repair the racks with some stuff we bought from Ace Hardware which did not include the tine caps. It didn't hold up for long, especially on the tines. I think the tine caps are a must. As an earlier reviewer posted, it is very important to remove ALL of the rust. I do not have a Dremel tool as he suggested but I used a 3 wire wheel on my power drill. It worked well but a dremel attachment would be more suitable because there are tight spots that are difficult to get into and I had to be extremely careful with the wire wheel as it is very easy to be concentrating on a rusty section and inadvertently scraping a perfectly fine section which of course causes more work and will unnecessarily take more of the goop. My suggestions would be to order more of this product that you think you will need. I initially ordered only one bottle thinking the racks weren't in that bad of shape but when I really got into the grinding I found out just how terrible they were. The other reason I say to order extra is because its better to have extra than to find yourself trying to stretch it out and not really getting the bare metal protected as well as you should. After I found that my one bottle wasn't going to be enough I ordered a 2nd bottle. After the Prep work was finished, I put a thin coat on the bare spots just making sure that the bare metal was all covered, not really worried about trying to goop it on too thick. Then after that dried thoroughly (about an hour) I applied  a pretty thick coat. I came up with my own way of putting the tine caps on too. For the first coat I put a thin layer on but for the 2nd coat I would just put a thick drop on the very top of the tine and then twist the cap on, turning it 3-4 times. Im not saying this is the perfect way to put the caps on but it seemed to work very effectively so you might want to give it a try. Like I say, I did the repairs about 3 wks ago so maybe the jury is still out but for right now, the racks look great! Im very happy. If something changes, Ill write another appropriate review. I would highly recommend this product, you can repair your racks for little $$ and time. The alternative is to buy new racks for your dishwasher and that just isn't practical.  One word of caution, this stuff dries very fast. You will want too keep your finger over the bottle to prevent it from thickening right inside the bottle. The directions advise this and I concur.
