After several painful years I finally learned that I'm grinding too much material off the axles (after 20-30 hours between myself and son's trying to make the axles last year right, a car that had zero work beat one of ours. That's when I started looking at fresh out of the box axles compared to ones we filed and found we did more damage than good).
So now I know my son's should not press hard on the file when removing the factory marks from the nails, but in the process I was thinking of ways to "rebuild" the nails with something stronger than zinc or at least smoother/better to make contact with the plastic wheel.
Is metal the only way to go? can an epoxy and or other material like fingernail polish (I know I'm reaching) be better than a highly polished zinc nail? (we don't have time to consider nickel this year as the race is only a few days away and I'm already stressed)
Thanks in advance
