For those recommending to hand your wife X tool to go do whatever the task is, is this a serious recommendation? This sounds like an opener to making it a real argument.
For stuff that is truly not worth it, I'll just go ahead and argue on it and not do it. For stuff that is an annoyance but will make her happy, I'll do it, but she'll partake in the hard work by having to hear me grumble about it for X hours or X days while I'm working on it. When the job is done, everyone is happy and it's no longer an issue.
Since I said it, I'll assume this is directed at me...
Short answer = yes it is a serious recommendation. As I stated, I'm not setting her up for failure. Just handing her the tools so she can see how much labor is involved in such an unnecessary proposition. Any paint line is going to be hidden well below the outer cover that goes over the base.
Perhaps I'm spoiled because my wife has never, not once, tried to boss me around and tell me how to do a project. I don't need to bow down to her rule and I would never want or expect her to bow down to mine. That's no way to live for either half.
If she had an unreasonable request, like this one, I'd walk her through the steps so she could do them and she'd see the effort needed and the results. It wouldn't be an argument and she would walk away from it either happy she learned something, or she'd be helping out because she understands that I don't see the payback for the effort the same way she does. No harm, no foul. We've been through this process countless times over the years.
There are some things I like cooked a certain way that my wife doesn't feel are worth the effort. I'll take care of those things and we are both happy. We both feel it's better to respects someone's limits rather than make them do something a way they don't want to. It's been working great for twenty something years of marriage so far. Getting easier as time goes by...
