WRONG AGAIN...

TUESDAY, APRIL 24, 2012


I know, I know...it's been awhile. What can I say? Life gets in the way and my writing took a hit. Let's move on shall we?

Recently I was reading an article that was singing the praises of WD-40 as a Godsend for woodworking hand tool maintenance. Whoa! Hold the phone! WD-40 in the woodshop? Are you kidding me? Everybody knows that WD-40 will ruin any chance of having finish stick to wood. Follow my thinking here - you're spraying down your hand plane after using it and some over-spray makes onto a component you've been lovingly preparing for finish. The WD-40 over-spray wicks into the wood and makes it impossible for any finish to stand a hope in hell of sticking to the wood.

Picture it, finish flows onto the wood, finish runs for the hills leaving fish eyes everywhere, your work is ruined, you start drinking and next thing you know, it's 20 years later and you're still drinking while living in a van down by a river.

OK. Hyperbole right?

Fine. It's a sub-compact, but the point is you can't use WD-40 in the wood shop. The writer even went on to claim that he had tested the theory by spraying WD-40 on a board letting it dry there and then having no trouble getting finish to stick.

Liar!

Now I'm on a mission to prove this wrong because ever since I starting woodworking over 10 years ago I was told that WD-40 is the devil of the wood finishing world. A can has never been in my shop in fact it has been relegated to the shed to help maintain things like shovels, rakes and other garden tools.

So I bring the WD-40 into my shop, carrying it like its nuclear waste, and spray down a piece of cherry. I left the cherry to dry and soak up the WD-40 for a few days and then started apply polyurethane just as I would to any other piece of wood I would finish. I applied three coats, sanded the third and put on a final.

Today was the reckoning. Today I show my woodworking knowledge and prove the goof to be dead wrong.

Well holy sh*t! The finish was perfect. Well, as perfect as I get finish. No bare spots, no fisheyes...just a smooth piece of finished cherry. Well.

Turns out you can use WD-40 in your woodshop. Turns out what I thought to be true wasn't. Hmmm...Just goes to show you that no matter how much you think you know, there is still more to learn. I don't mind being wrong, which is good because it happens often. I'm glad that I took the time to test this out because there really isn't anything better for rust removal than WD-40.

So all this time I've been searching out something to take care of minor rust when all I needed was good ol' WD-40....
