For final finishing try "Novus" plastic polish, usually sold with a companion container of cleaner. This stuff can return optical clarity to a motorcycle helmet faceshield. The tiniest defect is blindingly obvious when it is 1 inch from your eyeball, especially at night. I used to routinely chuck out faceshields, nothing I ever tried worked. Novus is the sole exception.
I haven't used it much on car parts, other than the instrument lenses and my tail lights.
The local motorcycle shops used to carry this stuff, but the last bottle I bought came from the internet. Last time I looked at a JC Whitney catalog they were selling it.
