Question: is le tonkinois varnish any good?
Answer: Le Tonkinois is very durable, but more coats are better than fewer. Approximately 6 coats give a good result, and since there is little or no sanding between coats they build up quickly. Le Tonkinois can be used on decks, it will not be slippery. Le Tonkinois is not brittle like synthetic varnish.
