Apologies if this one's been asked recently. I am new to this particulary forum. I have Zaino, I love Zaino, but my question is more about what to do in the long term. Because it is a polish and not buffed on, it will do nothing about removing oxidized paint. A friend said I probably won't have oxidation to remove. I'd like to believe that but am I right in being skeptical of that? If not, what would be the recommendation in addition to my obsessive layering of Zaino on to protect my paint? Many thanks!
