RUSTINS SANDING SEALER 500ML

Rustins Shellac Sanding Sealer contains pure shellac and alcohol with a special additive included to facilitate sanding when dry.
It should be used to seal the surface prior to French polishing and waxing, but is often used as a finish in its own right, as it dries to a hard, clear film.
Sanding Sealer should also be used to seal penetrating wood dyes to prevent them bleeding when varnishes containing white spirits are applied
