Product review (3 stars): Not the Greatest Expeience
It's been about a month and a half since we repaired our 5 1/2 year old Whirlpool Cabrio washing machine with this product.  Although this isn't a review on the washing machine itself, I must say that I never expected the amount of rust and decay in a machine that is supposed to hold water for its function as I found in this washing machine.  Just about everything was rusted badly.  We couldn't even get the basket released without lots of "Blaster" and time and effort.
The repair was much harder than I had anticipated, even with all the warnings and experiences I had read about in the other reviews.  It took us about 3-4 days to accomplish everything, and totaled approximately 7 hours. The youTube videos were helpful, and we didn't bother with the extra $100 tool, but in hindsight, it would have been very helpful.  If nothing else, rent one.  If you don't want to do that, buy yourself a short piece of pipe with which to set the top seal at the very end.  Nothing I read talked about that, but pounding in that seal was really hard without anything to set it correctly into the groove.
The repair helped with the loud noise when the machine spins, but after 6 weeks is seems to be coming back.  Most of the reviews that said things like "It is now whisper quiet when it spins" were written about the initial spin cycle, or at least early on in its new life.  I found that to be true as well, but it didn't last long.  At this point we are hoping to get more life out of the machine before having to replace it.  And will endure the noise until such time as it quits.  I will post again to let you know how long it lasts.
The bottom line is that this is a very poorly designed washing machine, and I am not sure that the effort to repair it will matter in the long run.
