woke up this morning to discover a thin crack in my countertops. They came preinstalled with the house, so I'm not sure what kind of material it is, but I assume its some sort of natural stone? The crack seems pretty small and only terminates on one edge currently. I can run my finger over it and can't feel a difference other than at the 2 or 3 places where it's chipped. Is filling it with Epoxy the best solution here?
