Limb skins from Alaska Bowhunting supply. You can pull them all the way down to the strike plate and over the grip if you wish but your gloved hand covers that part anyway.. Protects from scratches, very snug and keeps the value of the finish if you ever want to sell it.
Otherwise, don't spray anything onto it, lightly rub it down with auto rubbing compound. It will dull it right up the more you rub. Then to bring the shine back one day, just rub it with a high quality auto polishing compound. Presto, shiny like new.
