I was quite surprised how hard the rubber gasket was on my oil cap ('06 ap2). Replaced just the o ring. Was cheap enough from Honda. Now the cap tightens so much easier and smoothly.

The only safe way to get old paint off valve cover is chemical strip.
This is 100% true

Did your car exhibit any strange behaviour as a result of the old, hard oil cap gasket?

No odd behavior noted. No excessive oil use. Just did it as preventative.

The oil cap was always very difficult to remove. Like both hands and they hurt to get it off. Tightening it enough do it wouldn't vibrate loose required more effort too.

OK. Mine isn't like that then. Wouldn't hurt to pick up a new one I guess. A Spoon or J's Racing one is also an option

Late update. The rusty gas tank was causing the misfires from the fuel injectors continuously getting clogged by rust after having to take the injectors out and cleaning them multiple times. After replacing the gas tank and the fuel pump assembly, the misfire is finally gone and the engine couldn't be any happier since then.

How did you find the rust?

Maybe the PO ran without a gas cap or it was loose?

How does that even happen on this car?! Looks like you would have to run the tank dry, pull the pump hanger assy out and let the car sit outside for several years in a wet environment. Even then its not like its directly exposed to the elements. I don't get it.
