I think the best trunk paint being done now is a 2 step process; spraying the thick darker base color and spraying the lighter spots afterwards. There are a few resto shops doing a good job with this technique.
The original water base paint had solvent based paint drops that almost fish-eyed/popped open when drying. Without the original type trunk paint or the proper application gun there is no way to properly duplicate this. I don't think there currently is a single paint that looks quite like the original Norwood or LA trunk paint, which are both different.
