Here's what my current "old truck" paint job looks like, NM51. I'm pretty happy with it and it pretty much came about by chance. It is rattlecan Rustoleum (Dark Hunter Green). It's too "bumpy" to wax since it hasn't been color sanded but I found that you can use Meguiar's Quik Detailer on it to keep a dull shine and protect it some.
This is a hi resolution pic (895kb) so it will take awhile to download on a dial-up connection.
