We have been using the Chinese oil on the steel and timber on our boats for over 13 years. It is the most durable product we have found against the sea and salt air and the easiest to maintain.

My students often choose to use Chinese Wood Oil on their quality timber projects. Of course, the beautiful look and feel of the finished job is the main factor in their decision but also the ease of application and its low toxicity makes the job easier for all of us! Over the years, Summer has been extremely helpful in providing advice to my students and me regarding the range of excellent finishes and their application methods. Constantia is a great company to deal with for top quality and impeccable service.
