I am making a meaningful effort to finish the bodywork on my brother's Duster this year, and possibly even this month. I am at the stage of having to apply body filler and fiberglass to repair dents and holes, but all I have on hand are products I purchased several years ago.

I know the stuff that has been opened is unusable, but what about the filler and fiberglas materials that have just sat on a shelf unopened? Is it safe to use those?

Thanks from an autobody neophyte.

Bondo tends to dry-out over time and that makes it harder to mix and apply. Most body shops have a can of bondo "honey" that they can use to "thin-out" bondo.

Fiberglass resin will crystalize and the hardener "degrades" over time.
Crystilzed resin can be "repaired" by heating the container in hot water.
Degraded hardener will turn to a darker color and it will take longer to set / harden. ( it may not even harden completly)

The simple thing to do... mix and apply some samples and see if the material mixes, applys and sets-up the way you like & need it to.

Thanks Doc. I'll give it a try.
