e unchanged or, with clear or semi-transparent<br />
coating, looking much like the authentic surface.<br />
These coatings can, however create a plastic shine<br />
that changes an object’s appearance very much. The<br />
plastic look seems less obvious when the coating<br />
has a wax-like appearance (not too shiny).<br />
Protective coatings must either be very reliable<br />
or must be regularly checked and maintained.<br />
The conservator must make reasonably realistic<br />
predictions on a treatment’s protection time and,<br />
in choosing, be aware of the costs of any needed<br />
follow-up maintenance. Having the possibility of<br />
weighing options of treatment against each other<br />
by using a decision-making model can make the<br />
considerations of conservation more precise and<br />
thought-through before acting.<br />
