I have a follow-up observation. I last closed my roughly half full can of poly about June 6th of this year. I opened it again this afternoon, meaning that it has sat undisturbed for about 4 1/2 months. There was a very thin "cookie" of hardened poly on the surface that did not go all the way to the edges. I was able to lift it out in one piece. Below it was perhaps somewhat thicker, but very usable poly. The takeaway, I think, is that while you can't preserve opened poly forever, you can make it last a good while.

I used oil base polyurethane on over latex painted cabinets and turned a little yellow, I was told because I was supposed to use water based too coat, do you know of any east method to remove the polyurethane

I don't know how you would remove the poly without damaging the paint as well. Sorry.

How do I put the lid back on so it doesn't get stuck?

Patricia, I make every effort to keep the lid and the top of the can clean. I never shake or turn the can upside down. I also don't wipe the brush on the inside lip of the can. If the lid gets spots of dried poly on it, it won't seal. That can cause air leaks that lead to the poly skinning over. Hope that helps.

What about months

Umbrella, it is possible to keep opened poly for months, but I couldn't guarantee consistent results. The more air in the can, the more likely your poly will skin over. One secret is to keep the lid and the surface it contacts absolutely free of dried poly. Any dried poly will distort the lid and admit air into the can.
