Product review (5 stars): Benjamin Franklin said, "an ounce of prevention is worth a pound of cure".
We just bought a new dishwasher after our 18 year old one finally died.  I had installed similar tine caps when the old dishwasher was new and even after 18 years of use the tines looked like new.  So since I could no longer find the type I used 18 years ago I bought the Uber Goop kit.

I needed all, but 3 of the 150 caps.  I didn't have to use any glue or adhesive on the caps from 18 years ago, so following my order I was surprised that Uber Goop sent me an email with all the instructions and they said the caps will not stay on without the adhesive.  Additionally the instructions say to use in a well ventilated area and that the adhesive can be thinned with acetone, so I expected a terrible smell.  However, after removing the racks and setting up a table up outside to apply the adhesive and caps I discovered the smell wasn't that bad, of course this is relative and others experiences might be different.

The color of the caps match exactly the interior of our new Whirlpool dishwasher which is nice, of course I bought them for utilitarian reasons and although brand new they seem to be made of a quality material.  With any luck they will protect our new dishwasher racks and keep them look as good as new for the life of this dishwasher.  I confess my 5-star rating is a little anticipatory.
