Wax alone isn't going to bring back beauty. If you have full body paint, you may need to color sand and buff the MH or if you have Gelcoat buy some light rubbing compound such as 3M Perfectit II then buff the entire coach with an Dual Action buffer then wax the coach with a good quality Pure Carnuba wax.
