I understand the reasons why you're not supposed to use exterior paint on your walls indoors. What I'm wondering is could I paint a small item like,an end table that's going to be in my home with exterior paint. It's as simple as that.
Have you tried? What makes you believe that you can't?

You can do anything you want, but will it be optimum? Exterior paints are designed to be more elastic, to adapt to the extremes in heat and humidity found outside and the movement of the substrate that results. To this extent, it is gummier than interior paints. I don't even like interior latex/acrylic paints on furniture and cabinetry in general for this reason. If you put grandma's vase on it and go to move it a couple days later, you will have to yank it free. Don't even think about using it where the painted surfaces will touch. They will virtually become glued together!
A paint that I have been selling at Home depot and getting a lot of positive feedback, is the Behr water based Alkyd Enamel. It dries to a hard, durable surface. It levels nicely. It can be tinted to just about any color. It is also self priming over a sound existing finish. Over bare wood, it needs a primer. A quart, which would do your table several times over, costs around $15 bucks.
