Product review (1 stars): This kit will not repair badly rusted rack prongs. Tips are TOO short.
This kit will not repair badly rusted rack prongs because the replacement tips are barely 1/4 inch long!  You can goop on the liquid to cover what the the included tips don't cover but its looks sloppy and does not appear that it will last.  Unless you have this one hand to stop and cap the rust on a prong tip as soon as it starts - it will be too late to use this  kit.

I almost purchased a set of prong tip covers that were 1 1/2" long.  They would have been perfect.  I am repairing dishwashers in rental units and tenants don't bother to mention there is a problem until its a BIG problem.

I will not be purchasing this repair kit again.  Definitely not worth $24
