This means that when I squash a bug or spill tea onto a wall (it happens), I cannot really wash it off, because the primer rubs off and I see drywall. Result: ugly, dirty, shameful walls.
Have you seen this amazing technology? I wet the pad, I rub it on a stain, et voila! No more stain. It makes me want to buy a case and just rub every surface in my house until it is all unblemished. It is magical.
