I have found that the plastic used on early computers and computer monitors, that yellows, looks absolutely new and fantastic with a spray coat of "Arctic White" automotive lacquer, its called Holts Duplicolor in AU. This type of lacquer microscopically etches into the plastic's surface and it dries very quickly. It then becomes incredibly durable and scratch resistant and doesn't flake off the surface either.

To see a vintage (once turned very yellow) Apple computer monitor treated this way look at the photo on the first and last page of this article:

While chemical oxidation and bleaching may improve the yellowing, it will never correct it completely and the surface finish probably won't be as good.
