I finally got a good finish on a Ferrari, but sure as the world as soon as I got my last wet coat on, there was a spec of something right in the middle of the hood! I wet sanded down about 4 coats and thought I had it. I couldn't see it, and I couldn't feel it, and It is still there! Should I bite the bullet and sand all the way down to the plastic and just redo the entire hood, or can I get by with just an area of about a quarter? I'm so disappointed, because it was the lacquer finish I've ever done.
