Do not be tempted to use Poli Glo, it does look great but after five years on its is HELL to get off.
I have a good old boat like your and use a buffer a medium speed, clean the whole sheer and then go back with a coat of wax. I use Magyars, they have a kit of cleaner, buffer and wax for sale a your local chandler's I am sure. Make sure you use carnauba wax NOT silicone based.
Good luck, and esy on those elbows....
