A sheen can be corrected afterwards, within limits. To lower it: Wax Cutting, a wax loaded with pumice, reduces the lustre of an already polished surface, worked with a cloth along the grain. On shellac, the antique look comes from fine wire wool, two days after the last coat, for a deep matt that keeps the colour. On a varnish or a lacquer, the surest route remains a de-nib with 220 and a fresh coat in the sheen you want.
To raise it: Burnishing Cream, a very mildly abrasive cleaner, smooths and revives the lustre of a polished surface and enhances the gloss of a freshly applied lacquer or friction polish — Melamine Lacquer and High Build Friction Polish above all. On shellac, it is spiriting off, a rubber charged with methylated spirit alone, that brings the mirror up. On wax, it is buffing along the grain, with a cloth or a horsehair brush, to the sheen you want. An oil, though, cannot be made to shine: if you want a reflection, you need a film.
