For anyone interested, this is the
Motor Coater product that Kevin mentions. I have no knowledge of the product, but wouldn't straight out discount it's use with out some reasons and personal experience with the product. Being that it can be brushed on or sprayed, it may prove a better alternative to a rattle can for some folks. Before you decide, look at the customer reviews for
both products as it may shed some light on how good the product is or isn't.
