What are polishing compounds?

Supplied as a bar or in a paste, polishing compounds feature a blend of powdered aggregates combined with fats and wax. These range from super coarse to super fine and are designed to smooth and polish rough surfaces on metals, plastics and even wood. Applied by hand or used in conjunction with a buffing wheel, polishing compounds can rejuvenate old, scratched materials or prep and finish new projects.

Why polishing compounds?

Polishing compounds are an effective and efficient way of making scratched or damaged metal, plastic or wood shine as well as getting rid of any uneven areas or bumps.

When to use polishing compounds?

Polishing compounds are normally used when finishing a project or to give new life into old or dull metal. They are used by professionals and hobbyists alike.

Polishing compound types

While there are several blends of polishing compounds in their associated colours, each blend falls under one of three main types.

• Primary or first cut   -   Used to remove scratches and filing marks to thoroughly smooth a surface

• Intermediates   -   Cuts through ridges and rough marked surfaces to deliver a moderate polish

• Finishers   -   Also called finishing rouge, these compound types buff and finish a surface to deliver a high shine

Considerations when choosing polishing compounds

• Material - while many metal polishing compounds are quite versatile, others are only effective on specific materials like plastics and other synthetics.

• Application - whether smoothing rough edges and filing marks or buffing to a shiny finish, choose the correct compounds to achieve the application you want.
