I guess I COULD always just do the best I can and hope the paint covers and sticks, but I'm worried now!
Don't be worried, go for it! Your office will look great once you are done. Any minor damage can be patched, or you could always hang a picture over it. ;^)
Well, that's why they make drywall joint compound. Works like a charm, except it's a pain in the butt! You got to spread it, smooth it, wait for it to dry, sand it, then after all that, if it is nice and smooth, you can paint it! And if it's not nice and smooth, you can do all that over again! But after all that work, the wall will look GREAT when it is painted.
The painting isn't the hard part; the preparation is, right 2JM and ksen?
