I loved the way the finished turn out, just what I wanted and easy to work with.
I bought Out Door Oil to finish some southern red cedar chairs that set on my front porch. I wanted to bring back the colors in red cedar and seal and protect from UV sun rays. I didn’t want a gloss, just look like natural wood. They came out perfect! I applied 2 coats waiting 24 hrs in between coats. I applied with and stain brush and let sit for a few minutes and rubbed off what didn’t soak in off using a towel. Rocker.com we’re excellent to work with also. Delivery right on time.
They were bleached out by the sun before I applied the General Finish Outdoor Oil.

Great protection and beautiful finish
I've used General Finishes outdoor and indoor oils on decks, outdoor woodwork and indoor wood floors. It is a unique product that adds beauty with every application. I have always admired and wanted to duplicate the depth of grain and smoothness of finish that I've seen in old ships or the floors of 200 year old mansions. Wood that has been oiled and oiled for years. General Finishes oils are the only product I've found that produces that result.

Easy to use, great finish
I use this oil for wooden puzzles that I make and sell. It protects them against sun damage. Even though the wood stays inside, it may be sitting on a window shelf in someone's house. It also allows the natural beauty of the maple, oak, cherry and walnut that I use to shine through. Sorry this sounds like an ad, but it's how I feel.

Just what I was looking for
I applied this on a teak patio furniture set.I really like the way it turned out.
Leaves a non sticky, non glossy penetrating finish. No splotching.
It was probably mid to high 70s when I applied it (in the shade) using a rag and i found I needed to wipe off the excess faster than the instructions predicted. It starts to get a little tacky if you wait too long.
Looks great. Wife's very happy.

Fantastic Stuff
I called General Finishes and asked them what they would recommend for an application where something was outside in the sun and in the water so I needed UV and mildew protection. As well, it had to be non-toxic as people would have it in their hand all day. This would be cork handles on a fishing rod, but even if its outdoor furniture (which it was designed for), it is easy to apply, penetrates well, takes well to sanding and multiple coats and...feels great and smells great when it dries. People often remark how good my fishing rod handles feel in the hand. I can imagine sitting in an Adirondack chair or being at a picnic table finished with this stuff.

Is this a good oil for a cedar porch swing?
BEST ANSWER: Absolutely YES. We have used it on cedar for various projects, and the wood takes it up very well. This absorbs into the grain far more than polyurethane, and cures up very hard. Plus it has UV blockers to keep it in good shape even in direct sun. We used it on our wicker porch swing with superb results. Highly recommended for what you want to do with it.

can this be applied directly over arm-r-seal oil based satin?
BEST ANSWER: No, Outdoor Oil is a penetrating finish. It needs to be applied directly to raw wood. It is not a topical finish.

will it turn the white on cedar yellow ?
BEST ANSWER: If by "white" you mean the pale sap wood on western red cedar, then no, it'll just slightly darken the whole board, so relationship of sap to heart will stay the same, but darken both a bit to a slightly "wetter" look.

Can you paint over this?
BEST ANSWER: I don't see why not. It soaks into the wood and does not leave a glossy finish, so I suppose paint would adhere to it. I've just never tried it.

Would your outdoor oil be a good product for a marine dock?
BEST ANSWER: It is not designed for that type of use. However we have had customers use this on their pool desks. As long as you apply a coat every year it should hold up but it may not look that great. A clear finish outside will still allow the light to change the color of the wood.

can this be used as a covering for shelving or cabinet tops indoors?
BEST ANSWER: Yes. But please note that the product here is a linseed oil and will perform as an oil, meaning that it will wear off and dissipate over time. I would personally use a polyurethane or acrylic finish to make the surface smooth and easy to clean off any dust or grime that might collect.

Is it best to apply a finished coat like General Finishes exterior 450 varnish?
BEST ANSWER: In our opinion, it is best to recoat with Outdoor Oil annually to keep the wood looking beautiful. We live in an ocean salt environment, varnish isn't recommended.

Do I need to sand between coats during my initial application?
BEST ANSWER: This may not seem like an answer. I have used this oil 4 or 5 times, and never want to use more than one coat per year. With that in mind I do sand between coats, but they are a year apart. Because it is an oil and not a varnish, it will clog your paper unless it has dried for days if not weeks. I have used it on mahogany and massaranduba.

Considering applying it on a redwood gate that faces direct afternoon sun. Have used General Finishes 450 exterior, barely makes it a year before blistering. Would the oil finish hold up better without so much maintenance?
BEST ANSWER: I used this product on my front door that faces the southern sun. It has been three years now. I will probably refresh next spring due to slight fading. The product is thin and watery in texture, and is absorbed by the wood. Blistering is very unlikely.

Is this product good to use on outdoor teak furniture?
BEST ANSWER: Yes. You will need to re-apply it every year or every other year. Also this will not stop the Teak fro turning grey. If you want to keep the nice brown colors of the Teak you will either need to apply and oil stain first or tint the Outdoor Oil with a stain. About 1 part of stain to 3 parts of Outdoor oil works well.

The description says it can be applied over stain. I have an interior stain I wanted to apply it over will that be ok? I am applying it to a deck and they dont make the color I want in an exterior stain
BEST ANSWER: As noted by Scott, technically you can apply it over any stain once dried but the color may not hold up well. Our outdoor oil does have some UV protection but still may not keep the color for long.

Is this good for exterior doors?
BEST ANSWER: I haven't used General Finishes Outdoor Oil on exterior doors, but it has protected and made beautiful my decks and other outdoor wood products. It is the closest product I have found to give that deep and strong finish that I picture on the decks of ships and floors of classic old mansions that have been oiled and oiled for generations. I've found nothing else like General Finishes indoor and outdoor oils.

Can it be applied over linseed oil that has thoroughly dried ?
BEST ANSWER: Check with that product mfg. online and /or call, they let you know what to do. My take is it can applied over finishes but basically you have to powerwash and sand over it anyway.
I put Outdoor Oil on pine with sanding sealer applied and it failed in one summer. I'm sanding it and trying just the Outdoor Oil now..

Can this be used on exotic hardwood decks?
BEST ANSWER: I used this on a table holding a big green egg and it has given me a great looking finish. I cannot imagine it will not give excellent results on a deck. I would be more concerned if the deck has been previously coated with some other finish. This product needs and does penetrate the wood significantly. I gave my table three coats.

Can GF Outdoor Oil be used on freshly sawn green wood to prevent warping and checking?
I have new wood benches that have been treated with soybean oil and carnuba wax. Can I use this over top of them?
BEST ANSWER: The outdoor oil is linseed oil and other materials for UV resistance and mold resistance. If your benches only had the soybean oil, I would say yes. But having carnauba wax as well may limit the absorption of the outdoor oil and not work as well. It depends on how thick the carnauba wax was applied and how long ago.

what is sq ft coverage of the quart size? Thinking about using on garapa hardwood deck which is 250 sq. ft. Good idea? Does it have any UV protection?
BEST ANSWER: I only use it for small projects like my wooden puzzles. I do use it specifically for UV protection, though, since some customers put the puzzles on a window shelf, and they need to stay color fast.
