Open a 6 pack of air fresheners.

 

I worked for an airplane manufacturing company working with fiberglass and carbon fiber. If your talking about the smell of the fiberglass dust, maybe like if you sanded it smooth, we used acetone and alcohol to wipe it with and it would get rid of the smell quick, but leave its own smell until it airs out. Luckily both acetone and alcohol evaporate quick. If your talking about the smell of the resin, it shoulda been gone when it cured, unless you got a little messy, then you gotta get the resin out. Hope it helps.
