Q C I Direct, a catalog shopping source with a web site, has a product called Porc-A-Filler for fixing porcelain sinks, etc. (see the link below). I've never used it, so I don't know how good it is.
No; the sink can be scratched.
To effectively use porcelain polish to restore the shine and luster of your porcelain items, first clean the items with a mild soap and water. Then, apply a small amount of porcelain polish to a soft cloth and gently rub it onto the surface of the item in circular motions. Allow the polish to dry and then buff the item with a clean, dry cloth to bring out the shine. Repeat the process as needed to achieve the desired results.
Porcelain has a Mohs hardness of approximately 6-7, making it a relatively hard material. This hardness allows porcelain to be used as a streak plate in mineral testing to determine the color of a mineral's powder when scratched against it.
Different minerals produce different colour powders (know as the mineral's 'streak') when scratched. For instance, hematite has a red streak, calcite has a white streak and graphite has a black streak. There is also variation within some minerals, depending on impurities. It should be noted that some minerals are too hard to be scratched by porcelain, and will instead powder the porcelain, producing a misleading white streak.

The white line left behind when dragging calcite across unglazed porcelain is due to the abrasion of the softer calcite mineral against the harder porcelain surface. The powdery residue created is caused by the calcite being scratched off and deposited on the porcelain as a result of the friction between the two materials.
Those minerals that are harder than the unglazed porcelain streak plate will scratch it rather than leave a streak.

To identify old Chinese export porcelain with scratched-away marks, examine the overall craftsmanship, including the quality of the glaze, painting style, and the shape of the piece, as these can indicate age and origin. Look for signs of wear and patina, such as tiny chips or slight discoloration from use, which can suggest authenticity. Additionally, check for characteristics typical of specific periods, such as the presence of certain motifs or decorative techniques. Consulting reference books or experts in Chinese porcelain can also provide valuable insights.
