I have a coating that can be put on those gears that is far stronger than anything Husky puts on them. If anyone wants to guinea pig and pay to ship the gears to me and back, I will coat a set for free.
I'm not a gear expert but maybe there was an alignment issue when the original gears were cut from the factory (Misaligned/Binding) because mine were not at all that bad for being 'worn' but 50-75% of the time they would not even spin my motor over and the new gears start the bike almost instantly! As for a coating I'm not sure that would last but maybe re-hardened like a knife might do the trick, heat..oil.. and quench or whatever they do or forgot to do!! LOL
