: Although the glass won't change over time, the sizing is not as stable. Check
: out the Sweet Composites fabric information page - scroll down to the
: Fabric Finishes section.

It should work fine regardless. The sizing indeed helps the glass wet out but having the sizing not in perfect condition won't prevent it from wetting out, it's just slower.

Specially if it's stored properly it should last for years, many years.
