Sphinx® Retouch Varnish
A quick drying, light bodied, colorless retouching varnish, composed of crystal clear acrylic resin with a very volatile diluent. Retouch Varnish is excellent for use on parts of a painting that have dried flat in order to bring out their full wet appearance. It can also be used on paint not entirely dry, so further painting can be done. Protects paintings until drying is
complete, pending final varnish.
