Rustins Sanding Sealer is a quick-acting, shellac-based product. It is significantly thicker than shellac, and one coat is usually sufficient. It is therefore suitable as a fast-drying base for shellac, but also for subsequent oiling or waxing. The Sanding Sealer is pore-filling if allowed to sink in on a slowly rotating lathe and then ground in with a fine abrasive during drying. The created dust serves as a pore filler. The Sanding Sealer has also established itself as an independent finishing product, with the produced surface resembling the waxy feel of shellac.
