i like car pro pearl. i often find a really beat finish looks dramatically better the next day after curing. lasts a good while too.
Just recently got some Perl from a co-worker (mjlinane) and mixed it 1:1 to test on tires and trim. So far I like the darkening effect after a day or two and it does not run like Megs hyper dressing. Seems to do better with multiple coats on tires and trim. Even did the engine bay - WOW! Next to try is Gyeon trim to make it last longer on the other vehicle.
