Maybe I should be asking if ANYONE ELSE uses WD-40 as finish, because my brother does. He sprays it on, sands with 400-grit wet/dry paper, and buffs with an old cotton t-shirt. He gets spectacular results and the semi-gloss finish seems to last forever with no discoloration of the wood. Even his work in cherry, which is prone to oxidation, stays bright for years.

I haven’t tried it as a polish but it’s great for knocking out wasp nests!

Never. It might function like kerosene, which stains
wood. Some old timers were known to use used
motor oil. Many if not most oils will polymerize from
oxidation and thus sort of harden up on the surface
of the wood.

Guess I have never heard of that before. I will be interested to see the posts.

What Can’t you use WD-40 for, other than on your morning cereal or evening martini? I think Ill grab a piece of scrap tomorrow and give it a try.

I read somewhere that it’s been used to refinish hardwood strip flooring.
Wonder if it’s non-slip? :)

What my brother seems to be doing is creating a micro-filler slurry for the wood. I recently saw something on Woodsmith where Don was using a similar technique … but not with WD-40.

Okay, go ahead, knock yourself out with a good yuck. :)

He used WD-40 exclusively on the rotary box we published with American Woodworker. We told them what he used, but I don’t think they believed it because they never revealed the “secret”.

I never heard of using WD-40 as a finish but then again I haven’t heard about many things that work as a finish. I guess I will have to give this a go myself :-)

How does it smell after it…”cures”? The smell of it gives me a headache whenever I use it. I wonder if it repels water?

WE used it as a touch up for trim work that was already finished. Worked great.

I have seen others use it but I have never tried it as I think the smell would never really go away and that would not be very desirable.

For those who have been asking about a smell after it cures, there is none that I can detect.

I think the WD-40 finish must be a wooden clockmaker “secret”. That’s my brother’s primary area of interest. Makes sense, I guess.
