How does wax protect my chain from corrosion when its not a physical barrier and doesnt last very long on the chain itself. Is it solely due to its water-repelling properties or are there other factors at play. Given that wax isnt a permanent solution and needs to be reapplied regularly, what happens to the metal underneath - does it continue to corrode at a slower rate or does the wax somehow alter the chains surface to prevent corrosion altogether. If the wax is washed off or degraded, does the chain immediately start corroding again or is there some residual protection that remains. Is there a specific type of wax thats more effective at preventing corrosion than others, or is it just a matter of reapplying whatever wax youre using frequently enough.
