It was very easy to use. The directions were simple and to the point. Good product so far. We'll see how it lasts through the winter.
Even though there are several local options near my home to have windshield chips repaired for free I wanted to learn how to do the job myself. This kit is reasonably priced and was pretty simple to use. Time will tell if the resin holds up, but after two days it seems to be fine.
Every car owner must have.
