Are you not wiping down after use?

I keep a rag with a bit of thinner on it to wipe up excess. Never had it stick. The only thing I have trouble with in that regard is the quick drying stuff, but that's not this.

I mean I am no wood worker but it looks like there is product all over the threads, just wipe of the threads before you put the cap on ?

Same problem for me with that product. I've just resigned myself to having to use vice grips to open it.

I’ve tried several things to prevent it, since this is my go-to finish for simple projects. None worked, now I just keep a channel lock handy.

Not seeing a picture, sorry fellow lemming!

Some of it must have splattered onto this post... I can't see which product you're talking about.

I saw a tip for paint recently that I haven't tried yet, but it might work here too. If you get some painters tape and make a V over the top it acts as a spout and it never gets on the threads

Got something similar, I tested Teflon tape, it's actually dissolving, but I got (don't ask me where I got it from) thin paper tape, I do one layer over the threads, still gotta replace it every 3 or 4 times I open the lid - whatever, works so far for me. Just test some stuff, I'd recommend. Stay away from plastic tape, it could dissolve. Maybe a drop of oil on the threads? I'll try it, it came into my mind right now.

Guessing it might be a bottle of titebond ... If it is take a look at glubot
