I have used soluble nylon on very deteriorated paper some 25 years
ago. Later it was reported  that soluble nylon could not be removed.
It had also in some cases become sticky and grimy.  I stop using it.
The papers I have consolidated with 2% soluble nylon in warm
methanol are still very flexible with no changes in color.  Never
use soluble nylon on acid surfaces.  The objects must be deacidified
before treatment, and it is probably not possible to remove the
soluble nylon again.
