Preserving/polishing original faded paint ??

[KevinK7]

My '68 has original paint that I want to save/preserve. Some may call it patina, others just faded old paint.
Most searches I've done come up dealing with the heavy surface rust (or the debate on patina vs. repaint, which is not what I'm after.)
I don't want to CLR (not sure it would even be needed in my case anyway), and I'm not sure I want to matte clear over it.

What I'm considering is a light Scotchbrite scuff, then light 3M rubbing compound. My main concern here is I don't want to rub off all the paint that is left while doing this.
I've already started into the hood and think I'm going to keep going, but curious for those who have had similar condition trucks (that wanted to keep the original paint as I do), what did you do?
The net, even though I have an idea on what I want to do, just looking for methods/products others have used.

Thanks,

Kevin
