I made a tow hook cover by cutting off the end of an old rubber/plastic chain saw bar guard similar to the one shown in the link. These are probably available at a chain saw store. I formed the plastic so that it wedges between the hook and the plastic cowling under it, so that it stays in place. I've attached a few pics.
