Adding shine to old paint

I've been doing a little rubbing on the 1951 Chevy, and it still has the original "Forester Green" paint. I believe it's lacquer paint. It has pretty good shine for being 67 years old, but I'm wondering if I could add a little more. I don't want to clear coat it. I've tried wax and different spray on products, and so far everything just seems to add a light haze to the paint, no matter how much or little I apply, or how I rub it on. So far it seems like the thing that works best for the shine I'm wanting is WD40, but it's pretty short-lived. I used some "Wizard's Mist-N-Shine" and that didn't do any good, or so I thought. Sprayed some on, rubbed it like the instructions said, and the result was kind of a hazy finish with swirls, and it seemed to get worse the more I rubbed it. 
However...what I can't figure out...one spot, and one spot only, on the front of the hood turned out really nice. It almost looks like you clear coated it in that spot. The color was really brought out and is slick as glass. I can't figure out what happened there, because I used the same application/rubbing technique over the whole hood, and the rest just looked bad.

That seems like pretty good stuff, Shameless. I take it you use it? 

I had a 49 Olds that color and it was a beautiful color,  one car I wish I still had. I used good old rubbing compound and a lot of elbow grease, then Simonize I think it was called for waxing.  But the rubbing compound brought out the luster of that green paint.  It was a 12 year old car at that time.

Reminds me of my 1953 convertible I had when I was a kid
