Russell Guy,

Filmoplast 390 is not recommmended, sactioned or even allowed by the
Conservation department of the Library of Congress---all self-adhesive
(i.e. pressure sensitive) tapes are potentially harmful and should not
be used on paper  of any type. Even pressure sensitive tapes that are
called "acrhival" and sold by companies like Gaylord cause serious
problems later on.
All repairs to valuable maps should be done using Long-fiber repair
techniqiues that employ wheat starch and specially prepared paper.
Heat-set tissue should not be used on anything of value because of the
iron needed to due such repairs generates a great deal of heat which
reacts differently depending on the media and substrate.

Hi all,

Thanks for the very numerous replies about map repair tape and
spray-on
waterproofing.  A summary of the results:

Consensus was very definitely for "Filmoplast P90" self-adhesive paper
tape
by the German company Neschen.  3/4" x 164" roll sells for about $20.

Gaylord had a selection of cloth tape with either self-stick or
water-soluble adhesive.

A third option was Archbond heat-set tissue by a British firm.

For spray waterproofing, the consensus seemed to be Map Seal:

Again, thanks for all the replies.

Cheers
Russell Guy
