Wanna restore my cranks...

[Escapee..]

How about just putting on a crank protector, certainly the quickest and cheapest option.

Have them Cerakoted.

 

If it's strong enough for rifles and manifolds i'm sure it'll be good on cranks.They can do any colour you want.

 

 

This would also work well, used often on motorcycle parts and it's hard wearing. Who does it up North?

For the price of ceracote you can buy new cranks.
