Check out my thread "finally polishing my 34'; towards the end of the thread soyboy has pics of his 99 that he is polishing. I would think the aluminum will be similar to your 93.
Having a bungled, half finished (or in my case, poorly attempted) polish by the previous owner certainly helps to push the decision to polish!
It looks really good when it is done! Make sure you post progress pics if you go the polish route.
