It's important to know what you can do and what you can't do with a kit like this. They work great on chips, but anything with a running crack is a bigger challenge. We had little to no luck repairing a crack with the kit, even though they claim it works, and provide instruction in how to do it. We just couldn't get it to look right despite a number of attempts. But for chips and bullseyes it was amazing.

Important! Don't perform this repair in the hot sun. It will cause the resin to harden too quickly and your repair won't be as beautiful as it could be.
