Product review (5 stars): Easy enough.  Looks good. See tips below.
This product did the job nicely.  We had very bad rust on the bottom rack of a dishwasher in one of our rental properties.  We were going to buy a new bottom rack for about $165 but came across this and thought we would try it for the $20 something dollars first.
After reading the reviews, someone suggested that 2 people do it toghter since the liquid vinly in the bottle dries quickly.  Well it does and with the 2 of us(my husband and me) the repair went relatively quickly.  We highly recommend 2 doing this together if possible, one to paint the times and one to put on the caps.  Also, we had a lot of rust on some of them and had to actually clip the top parts of the tine to get rid of the rust.  This was the most diffcult part since the tines are made of pretty heavy metal.  Also, be sure to WEAR GLOVES when dealing with the rusty part, whether sanding it or cutting it.  I did not have gloves on and got jabbed with a rusty tine.  Had to make a visit to the doctor's office the next day to get a tetnus shot. But in the end, the rack looked good when were finished and except for the tetnus shot, so far it looks worth it.  I will post again if they do not hold up.
