What is Mr. Cornwall's Super Duper Dark Oil? // Odie's Oil Products 

Applying Mr. Cornwall's Super Duper Dark Oil | Natural Wood Finish 


Mr. Cornwall’s Super Duper Everlasting Dark Oil (SDEDO) is a unique rich dark finishing oil, containing natural reactive and oxidizing oils that darken wood. Its thinner formulation and look is similar to that of a danish oil but with the strength, durability and all natural, food safe qualities you’ve come to expect with Odysseus Cornwall’s Outstanding Oils and Waxes. Food safe, free from petroleum derived solvents and non toxic, containing no added driers, heavy metals or part 2 catalyst.

Mr. Cornwall’s Super Duper Everlasting Dark Oil provides a deep warm look, creating a slight amber effect upon application that will continue to darken with age depending on wood species and UV exposure. It works hand in hand with Mr. Cornwall’s Creative Colors by where the pigments are added directly into the oil to create an easy to use stain. When used over Odie’s Oils or Wood Butters as a topcoat it will actually step up the sheen! SDEDO penetrates, cross links and bonds molecularly becoming one with any surface it’s applied to. It does not instead sit on top as a shell or film like conventional finishes. It protects, stabilizes, beautifies, densifies and enhances any surface easily, safely and naturally. It cures fast and hard while also remaining flexible. This means it will never peel, flake, chip, delaminate, wrinkle or leave unsightly white scratch marks or cracks!

Mr. Cornwall’s Super Duper Everlasting Dark Oil can be applied to everything from wood, metal, leather and concrete to plastic, vinyl, stone and more! Recommended for interior use only. Great for all species of wood, exotic and domestic. Formulated to work on even the oiliest of woods. Finish flooring, whether it be wood, concrete, terrazzo, bamboo or even cork! Use it on fine furniture, cabinetry, tables, bar tops, wood cladding, countertops and bar tops, bowls, charcuterie and cutting boards, spoons, knife and ax handles, toys and more! The list goes on and on!

Mr. Cornwall’s Super Duper Everlasting Oil is a proprietary blend of the finest oils and waxes, born out of inspiration, hard work and a driving need to solve problems. The culmination of 40+ years of research, development and field testing performed in the most extreme environments produced a revolutionary product that out performs and out covers the competition with unparalleled protection, versatility, beauty, durability and value, all without the use of ANY toxic chemicals, petroleum derived solvents, isocyanate hardeners, heavy metals or added driers.

    Sailboat Sole Boards

    Posted by Michael Kasimier on 21st Mar 2023

    I used the Super Duper Dark oil to finish on 51 year old sailboat mahogany cabin sole boards following a sanding down to bare wood. Extremely happy with the results. I used two coats of the SD Dark and a top coat of Odies original for extra build up and protection based on recommendation from the company. Very rich colors, so far a low dust build up with foot traffic. I would highly recommend

    Worked just as advertised. Not quite as dark as expected, but could not be more simple to use and results are excellent! I used on Rustic Walnut.

    I've been a woodworker and furniture maker for 45 years. Nothing is better than odies for any project. Outstanding results with no effort.
