Buffing details

Buffing is performed by applying an "abrasive" to a rotating buff.

Metal polishing "buff polishing" removes small scratches by manually polishing each one by a craftsman.

From general metals to aluminum die-cast, zinc die-cast, titanium and other difficult materials can be beautifully finished.

Please feel free to contact us as we can handle even one-of-a-kind items.

Please contact us as it is possible to polish resin materials.

We only support cleaning of products buffed by other companies. (Polishing residue removal, buff residue removal)
