if you can find it, there is a product called 'Liquid Plastic', apply it over the entire coil thread and spanner nut once the desired height is attained, then just liberally brush on the product. 3 or 4 coats will provide you with the protection. In spring/summer just use an exacto knife and peel off the plastic. Also spray on some PAM before covering, this will make the peeling off much easier. This is just one method.
