I always check my straps, seats, bolts and everythign that may come lose or make noise over a period of time, if bolts are rusty, I replace the, if straps are frayed, I replace them. If theres any rust on the stands I wire brush the section, hit it with a brillow pad, wipe with warm water, let dray, prime, let sit, prime again, and then put 2-3 layers of outdoor paint.
