If you go the white out fluid route, there are some bottles that use mini-sponges versus the old brush-types which are easier to apply. If you're worried about dripping on/in your machine with fluid, there's now also a variety of small handheld dispensers of white out tape which allow some incredibly precise use at the level of individual letters. Scroll the paper up a line or two, white it out, scroll back down and be on your way. (I only do this for things approaching mission critical applications; generally I just x things out or overtype and continue.)

My typing technique has gotten better using a typewriter versus computer keyboard.
