Epifanes Clear Varnish is a high gloss traditional varnish, based on tung oil phenol and alkyd resin with excellent outdoor durability. With high UV filters, Epifanes Clear Varnish protects against discolouration. For use on barewood and intact existing varnishes. For inside and outside above the waterline. As used by us at The Bosun's Locker - certainly one of the best varnishes on the market!
