Is there a way to remove what appears to be oxidation? Does it just take a lot of poshing and thats it or are there specific products that may restore the shine?

 

Try using clay, like Mother's claybar kit.

I used it for the first time last weekend....my paint looks pure white again. It works!!

 

I use clay and klasse all in one cleaner/sealant with an orbital it seems to work. One of my buddies had hard water spots on his M that he just couldnt get out and he tried vinegar (he read it somewhere on a detailing forum) and it took it right out.

 

Great tips!
