Rainbow wiper inserts

["Dan Gillitzer" <dang@ticon.net>]

Well, I made the comment that someone should note what refills work with the
original Rainbow blades. Having some success with Anco U-16R. U means
Universal I guess. The "W" wide series and "N" narrow series both seem too
narrow. I chose the 16" U series as these are 8" blades so I can get 2 sets
out of 1 pack.
