Epoxy filler for tile cracks

[DrJohnZoidberg]

When the guys were installing a door stop in my one bathroom they over-tightened the screw and it created a few hairline cracks around the area, it's really not worth replacing the entire tile but I've seen you can use colour match epoxies to fill small cracks like this.

Has anyone done this? What product did you use?

Toothpaste in previous rental just before we left. Couldn't see a thing.

I've been hearing good things about Bond Boss. They have a couple of products to seal and cover cracks. It dries to a clear coat.
