I dont worry about it. The bow itself as well as the cams are rust/weather proof already. The strings/cables when waxed are fine.

The eclips, and screws that hold down sights, rest, etc can either be replaced with stainless (did this with my bowfishing bow 100% ss), or can simply be replaced each year, the thread count and bolt size can be easily found, if not, I have them written down for those interested.

When I get in from a rainy hunt, I shake off the bow, and lay it down to dry. I pick it up again when I head out for the following hunt/target session.
