Product review (5 stars): Good alternative to buying a new dishwasher
This dries very quickly, so be sure to use only a little at a time and put the cap back on as soon as possible.  I followed the directions, sanding the rack where there was rust and waiting several days (I waited about six) before using the dishwasher to let the vinyl cure.  I also applied it more than once where I thought it was needed.  I've used it twice since then, and the patching seems to not want to separate.  If you remove the dishes immediately after the dishwasher is finished, the dishes may feel like they are stuck to the patching, but just gently remove them.  I didn't notice any vinyl stuck to the dishes.
Also, the color was not a perfect match, but my rack has probably faded considerably since it was made.
