Translation of "Polishing" in Finnish

There are so many fine scratches and dents on its surface, it's no use polishing it.

Pinnassa on niin paljon pikkuruisia naarmuja ja koloja että sitä on turha hioa.

It´s an excellent piece of work. You´ve certainly been polishing your skills, haven´t you!

Erinomaista työtä. Sinä olet varmaankin hionut taitojasi kovasti.
