Elfy Super Crystal Varnish is a distinctly full bodied transparent varnish with an ultra violet filter which is designed for exterior wood work. It gives a beautiful gloss finish which is wear and tear resistant, thus durable, also resistant to sun, salt water and salty air. It is easy to apply evenly to produce a high-build finish. Elfy Super Crystal Varnish is recommended for wood work on boats and yachts inboard and outboard and outboard above the water line.
