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

Applying Super Duper Dark Oil | Non-Toxic Wood Finish 

Mr. Cornwall’s Super Duper Everlasting Dark Oil (MCSDD) is a unique rich dark finishing oil, containing natural reactive and oxidizing oils that darken the wood. It's 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 top coat it will actually step up the sheen! MCSDD 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.

    I had used the way and the butter on a different job. This time I used the super duper dark oil on 500 sf of Oak flooring I had milled. I also used the powered pigment to darken the oil. Loved it. worked great and looks good.

    Cornwall Super Duper Dark Oil - Awesome

    Posted by Sam Gladstein on 8th Mar 2023

    I have been using this company's products for a few years and every product is outstanding. This is the first time I used the Cornwall Super Duper Dark Oil. I chose to use it because we were doing a lot woodwork in white oak that required hand application. While the Odi's dark is great, it's a bit more labor intensive to apply due to the thickness of the product (although we used the Odi's oil on desktops for this project along with Odi's Butter and Odi's wax). For the volume of hand applied finish we had for this project, we decided to use the Cornwall oil for faster application. It worked as we hoped and the finishes are awesome. It was so much easier to apply in large quantities (although we probably wasted more product than we needed to due to our application process). I highly recommend this and all the Odi/Cornwall products.

    Hardwood Floors

    I used this to refinish 900 sqft of 100 year old hardwood floors. It was so easy to work with, looks beautiful and I will continue to highly recommend all Odie's products based on the wonderful experiences I've had using them. I like the dark, brings out beautiful tones in the wood.
