JeffW: Menzernas HGAS (High Gloss Acrylic Shield) is a QD whereas AJT is a standalone sealant.
I would not apply AJT over a carnauba (it is not QD)....smearing and lack of proper bonding are likely. Now Maxwax, Natty's or Souveran over AJT rocks.
Don't agree with you about HGAS, with all due respect. HGAS is a spray sealant and can function as a standalone LSP. AJT seems to be formulated a little thicker than HGAS which makes it tougher to spread, IME, but other than that the results seem to be fairly similiar - that nice acrylic glossy shine. I can't vouch for durability as I've never left either alone long enough.
I have traditionally used both as QDs over WG or BF. After putting on a number of WG coats, I then will treat after each wash with the acrylic spray, simliar to how others would QD.
Also, just reread my original post and it does not seem real clear about another point - instead of saying I like acrylic sprays on top of carnauba, I meant to say that I prefer the looks of acrylic instead of carnauba.
