Tamiya Polishing Compound Finish closes the printed three-part progression after Coarse and Fine. Its extremely small, uniform abrasive is produced by a special process to refine slight imperfections and develop a deep mirror finish. Tamiya states that it leaves no polishing scratches of its own — a claim he prints for this grade alone. The maker identifies painted surfaces and transparent parts as core uses, while the English page also includes pre-paint work and metal parts. Residue is removed with water when the polishing work is done.
Finish is the last grade in Tamiya’s stated Coarse → Fine → Finish order.
The uniform abrasive is designed to produce high gloss without introducing fresh polishing marks.
Painted surfaces and scratched transparent parts are named directly on the Japanese product page.
The English listing additionally identifies use before painting and on metal components.
Remaining paste can be rinsed away using water.

Notes · Q & A
What does polishing compound do after sanding?+
Polishing compound uses a finer abrasive action than ordinary sanding to reduce surface haze and fine preparation marks. It is a finishing step rather than a substitute for levelling deep defects, which should be corrected before polishing begins.
Why do polishing compounds come in different grades?+
Different grades trade cutting action against final gloss. Starting with the least aggressive grade capable of correcting the surface reduces unnecessary material removal, while skipping a needed intermediate stage can leave earlier marks visible or make the final stage take longer.
What should I use to apply polishing paste?+
Use a clean, soft cloth, foam pad or applicator recommended for the product and surface. A small, controlled amount is usually easier to assess than a heavy layer, which can spread residue and obscure whether the finish is improving.
Can I polish clear parts or painted surfaces?+
Clear plastic can often be polished, although deeper damage may require prior correction with suitable fine abrasives. Paint hardness and compatibility vary, so allow the coating to harden fully and follow its maker's guidance before polishing. Remove residue only with the cleaner specified for the compound.
