Product review (4 stars): Good Repair Kit
The repair of the rack went well, although it is extremely time consuming depending on the condition of your rack.  Mine had many places where rust was coming through cuts in the vinyl.  This kit was way cheaper than the cost of a replacement rack.  It is now 6 months after the repair and some of the repair locations are starting to rust again, so don't expect this to result in a permanent repair.  No matter how much cleaning, rust removal, sanding, polishing you do to prepare the rack for the vinyl repair, water will always find a way to start the damage over again.  That being said though, this is a great way to extend the life of the rack if you're not ready to spend big bucks on a new one.

Another thing to note, this chemical used as a solvent is very volatile (evaporates quickly and strong smell).  I found myself having to replace the lid after each time I opened the bottle and shake prior to opening each time.  Otherwise, the polymer would start to solidify very quickly.
