I must admit, I like the JJ1 too.
I've had a '68 Hemi GTX for 30 years, just started working it this year. New paint is on, I used PPG DBC. JJ1 "gold ember poly" is not available in DBC, so they matched it with one phone call to PPG, it really pops in the light. I haven't cut and buffed yet, but the clear is all on.
A lot of folks give me trouble for keeping it JJ1 instead of something more flashy, but i shrug my shoulders, say "it's a factory hemi car, i'd like to keep it original. If I wanted purple, I'd build a clone!
