Topic tags/keywords: question finish can oil

I just bought a quart of Watco Danish Oil. I am not weak; my hands are not arthritic. The frickin’ can took 10 minutes to open! The stupid soft plastic on soft plastic “gears” that engage when I “push down and turn” just slide past each other! I had to apply a large wrench to the cap and it STILL was a battle…holding the wrench tight on the cap, pushing down on the cap, and turning wasn’t as easy as it sounds…the can had to be fixed in place.

When I finally got it open, a cardboard cover was stuck in place. When I peeled it off, a thin layer of ‘paper’ from the cardboard remained. Removing that left bits of it around the rim.

Now that it is open, I don’t want to close it… but I have to.
In the past I’ve taken plastic from a shopping bag to put between the cap and can to ‘seal’ it. It works, but isn’t wonderful.

Can I Vaseline the cap’s threads without ruining the product if they mixed?
Any advice for this dilemma? Am I the only one?
I am aggravated over this stupid thing! HELP!

Before I open a fresh can I take my bottle opener/paint can opener (a screwdriver will to) and pop off the plastic cap (straight up).

Now you can work with pliers if you need to.

Watco is sticky stuff so it gathers on the threads and makes its own gasket! Cool!

Just have the pliers on hand whenever you need to open the can. In over 30 years of using the product I’ve never had to throw out a can that wasn’t empty.

I’ve had that happen with other products and used a pair of arc joint pliers to get it off. Squeeze tight enough turn, it will come. You could also warm it up with a heat gun to soften the bond the finish has caused, but that always seemed to be more hassle to me (and maybe not quite as safe). I suspect the thinner in the finish could dissolve some of the vaseline and allow it to get into the finish…thoough I’m unsure what would happen. Likely nothing, but I’m not sure. I would clean the thread of the cap and the can with MS, and then just put the lid back on, or empty the whole thing into a canning jar and put a food storage lid (one of the plastic ones) on it. It keeps longer in the frig…

I too, remove the plastic cap prior to using the product.
Also, consider cleaning the threads after each use will help.

Like others I usually remove the plastic cap.
If I get lazy and the threads gunk up I go straight to a pair of channel locks.
Good luck!

I bought my first can of watco the other day. Same problem. I’m not weak. Pushed down and turned, it slipped. Use pliers in one hand, pushed down with the other hand, it slipped. Took a screwdriver and pried the lid off. Now when I put it back on it comes off as it should by pushing down and turning.

Same here, trash the plastic piece and get the channel lock pliers. Works every time.

So I’m not the only one!
As I said, this was a brand new can from the store…but I will wipe off the threads w MS after each use. I assume then that you guys use a screwdriver or some sort of pry-bar and fight to pop off the ‘outer’ plastic cap.

Sheesh!!! I wonder if WATCO is aware of the efforts we expend to use their product… My next can of finish, I will look to see if competitors opted for a different kind of cap…IMHO, the one on this can is inappropriate for this use. It is hard to like a product when using it involves a battle…the manufacturer should solve this problem for us.

In fact, I just contacted them online (RustOLeum Corp.) and told them how I feel. ARGHH!!! No I didn’t… their Contact Us page doesn’t work! I filled it out…at the bottom it says they use a system to ensure a human is submitting the form (I assume a Captcha method) but there is no method on the page and the Submit button does nothing. (I’m using IE10) Apparently they think all their products are perfect since nobody has contacted them to say otherwise…go figure! (Update: I refreshed the page. IE said only secure content is shown. The first time, I left it at that. This time I said to Show All Content and the Captcha appeared. Fortunately, I thought ahead and Copied my message before Refreshing the page so I didn’t have to re-create it from scratch. Now y’all know what I learned about that! ) Ok…my comment successfully submitted to RustOLeum. I’ll let y’all know what their response is.

Meanwhile, I welcome any other tips on how y’all handle this issue.

I remove the plastic to on that and everything else I can. I know why they it there, but I reserve the right to remove it. Now a pair of pliers solves the problem. A rag to remove the spillage after use is a big help also.

Channel locks or vise grips works pretty well.

Hmmm… I know where you’re coming from, but this isn’t computer-related. I’ll bet it would take a 4-yr old at least a minute.

+1 to the channel locks

After it’s been opened the first time, I put a wrap of plumber’s Teflon pipe tape around the threads. Usually this prevents me from needing the channel locks for a second time.

I tried the Teflon tape in the past, but it didn’t want to stay in place. That’s when I went to plastic from a shopping bag, which wasn’t so great, either.

Today is Monday and I’m hoping to get a reply from RustOLeum, who puts out the Watco Oil product.

Yep you are not alone its a conspiracy against old people with failing eyesight and the most annoying micro dot printing on the lid and direction labels as well, I need glasses and a magnifying glass to read it these days.

A pair of vice grips works every time for me !!
