I have been fascinated to follow this discussion, but before it finally closes I thought we should just confirm that everybody is talking about the same thing. I have never heard of "whiteout" before, but I guess that it is a trade name for a proprietory product used for correcting typing mistakes. There are many similar products available in the U.K., under names such as "Snopake", "Tippex" and "Liquid paper" - some of them applied by brushes, pens or rollers, and some which claim to be "solvent free" (presumably water is not a solvent in their vocabulary) or "environmentally friendly" ("contains only natural solvents", whatever they are!). They also come in various colours, and some have their own thinner fluids. Do the comments which have been made about "Whiteout" (should it have a capital W?) apply to all of these? Another small point that needs to be raised: presumably "Whiteout" is used to give a white area on which numbers will be clearly legible. Is the alternative suggested, "Acryloid B-72", transparent, and if so will it be adequate to use white or black ink depending on whether the colour of the object is dark or light? Is any there any acceptable opaque material which can be used when necessary?
