Actually, the idea to put a clear coat on it was more to protect the paint and make it easier to wash it. I did the left side of my car and it look pretty good and shinny.
But the problem is that I use foam to apply the paint( because I found, after applying one coat, that the brush didn't work really well) so I can't put grease on my nissan logo. So Is it possible to sand it back to metal ?? I'm asking because I just read on page 5 ( I think or 4) that it take way too much time to sand it back to metal...
