My proof of this: latex-based paint. It looks great on paper: cleanup is easy, the paint is easy to apply, the dried product is water-resistant, and it doesn't smell bad like oil-based paints. What's not to like? I'll tell you what. My house hasn't been painted in 5 years, and doors still stick to their door frames. I nearly need a crowbar to open the closet doors (I just leave one of them open all the time), because the paint on the door sticks to the paint on the frame. Also, latex paint won't stick to any other kind of paint, except on really porous surfaces like drywall. So if you had the good sense at one point to paint with oil-based paint, little bits of your latex paint will peel off every time you touch it. Surely there's a better way ...
