Does your favorite collectible have a flea-bite chip or nick? Have you tried to repair it but is still visible? I may have a simple repair using a few items you already have in your home that may be of some help. You will need a bottle of  clear fingernail polish,  nail polish remover,  a Q Tip swab and a collection of colored markers.

Clean the area of the nick with the nail polish remover using a cotton Q tip and let the area dry. Apply a nail polish droplet to the affected area.  Depending on the size of the nick, calculate the size of your droplet and let that dry. Don't apply the nail polish by brushing across the nick. The droplet will eventually level itself out as it drys. A hairdryer may be used to speed up the drying process.

The idea is to fill in the space or chip. As the droplet dries, it fills this space and levels out to the surrounding surface edge.  Once it dries, you match the color by applying the tip of  the matching color marker to the affected area. If you are not completely satisfied with the color match, you simply wipe off the coloring with the polish remover and start the coloring process over.  Be sure to wipe off any excess color run-off.

When you are satisfied that the color matches perfectly, you  apply a final coat of the clear nail polish over area with a brush stroke. One application works most of the time. When the repair is complete, you will see  that the clear nail polish gives the affected area the glaze look that matches the factory glaze. Black will be the easiest repair.  I hope this is helpful and you will see that it actually works.
