I went from 85RD to WG paint enhance to Fuzion. While I tried this only on one bumper, I feel this added value. If you have the stuff, give this a try like I did.
Do what Mike Phillips of Meguiar's always says: Do one panel without the paint enhancer and see if you like it. Then do another with the paint enhancer and see if you like that better. If it doesn't look better to you, don't bother with the rest of the car. If you like it better, then you'll know what you'll need/want to do.
