I bought a set of Krypt HLCD and during shipping the grill moved on one of the speakers and was rubbing on the woven speaker cone during shipping. Thankfully it didn't tear the cone or do anymore damage, but there is a white dust on part of the cone and I can see some of the woven part is dull not as the rubbing action had rubber whatever coating was on the woofers.

I can exchange them no problem but its more trouble than its worth esp since shipping is a killer.

Can I apply some sort of epoxy or super glue just to coat the cone to seal it up again?
