4yrs ago today I formulated Bill Nelson's "wolfers pack" formula.. using quality ingredients as he did.well, almost formulated it. There was a few other things I had to do after the first step.
I went to pop the top today to fill a small bottle to test on the line and the lid is stuck solid. Basically glued on..
Soooo, once I figure out how to open it, I'll let yall know how it works on the line. Last time I opened it, 3yrs ago..it smelled like money.. the battle continues tomorrow to open the jar

Any solvent, or the cap ran under hot water should do the trick. Still may need to use a little elbow grease but should help aid opening the jar. If not maybe the experts can help.

Got a gallon glass jar of fish oil with same problem. When you figure it out let us know. Not in a big hurry to open mine, was just going to strain it when I realized I used to be much stronger....

couple relief cuts with a dremel...

Hot water will expand the lid a bit making it easier to twist

If it is a glass jar with a metal lid you can take a table knife. The dull one you use to butter bread. Hold it by the blade and tap all around the top edge of the lid with the handle part. It will loosen the lid. you may have to do it a few times. Works for me on bait jars 4 ounce to gallon size.

That's the same method I use but with a wood dowel rod or hammer handle

Channellock pliers have always worked for me.

I use pliers

If you use a wrench or pliers. I'd still run the cap under hot water, or give it a little squirt of olive oil / vegetable oil. Should help a great deal to keep from compromising the jar or lid. Also will not have any effect on your bait or lure. Jmo imo imho jm2c

Thanks for the help. I almost didn't recognize the lure once I got it opened. 3.5yrs of aging has really worked out nice. I can't wait to try it.

Got some jarred and set out some new ground today to test it. Mostly flat sets. I remade a coon catch on a scent post set and turned it into a trash pile walk thru, it's my best producing remake once the spot is all torn up with grass and debri.. loose dirt.. I make 2 mounds out of the debri about 16-18" long, just as wide as the jaw width of the trap.. poke small holes on both sides of the mound on the bottom center of the pan
Anyways, I'll hopefully have good results in the next few days. I'll keep y'all posted. I set on lots of fresh sign, it'll be right under their noses. Wish I had some game cameras to see how they react.
