I have some moderate oxidation on my hood, roof and spoiler. The finish is much duller than the rest of the paint but the surface is still smooth. What are my options? Any one have experience buffing it out? Thanks for any useful advice.

 

I'd try some polish then wax it. I like the "professional" (tan bottle) meguiar's show car glaze. Post in the detailing forum and you'll get plenty of feedback on other products.
