I bought a primer from an auto parts store. I water sanded it down with 400 grit sandpaper, but portions of it looks rough and like it may have pinholes in it. The paint wouldn't cover it up. What could that problem come from?
I have a 2007 Ford Fusion. The factory radio plays but the cd portion doesn't work anymore and it won't let me get the cd's out. Any trouble shooting suggestions?
