Carpentry odor Q: Bondo indoors?

[Psurfer]

A carpenter wants to save a large plank that has some older visible termite damage by filling in the termite tracks w/Bondo. I trust his judgement, but not necessarily his sense of smell; this is in a bedroom in a house that will be put on the market very soon. Will the lovely Bondo smell be detectible for days and days, even after painting over it?
