A temporary spray varnish that doesn't turn yellow, ideal for safeguarding freshly completed oil paintings. High-quality sprays for oils, acrylics, pastels, charcoal, and pencil. Paints that have been completed are protected with varnishes. Picture varnishes used in fine art should be removable to allow for future painting cleaning. Because of this, Winsor & Newton designed every one of their Professional spray varnishes to be easily removed.
