Unless your have remove a high amount of metal off your element
you can re-coat it.
All heating elements rely on a layer of oxide grown around the
element to protect the wire. Anytime you damage the oxide layer
it should be re-coated, this is true for any type of heating
The way to do this is to run the temperature slowly to its
highest point and leave the element on for 24 hrs. It is very
important that the element not be covered. As in a kiln, the
oven door should be left open. On a small enameling kiln leave
the top off. The air around the hot element will re-grow the
oxide back on the element.
If the wire is damaged it will eventually open up. Any time you
buy and type of equipment, with an expose element wire, if you
take the time to properly grow this oxide the life of the element
will almost double. This process should also be done anytime you
scratch the element wire.
At any ceramic shop you can also buy ceramic standoffs to keep
items away from the element wire.
