Can you put Klasse SG or Jeff's Jett over a QD?

I use 425 QD a lot after a wash; also, PoorBoys SW is a favorite QD of mine as well. My base is AIO and the lsp is Werkstats Jett acrylic sealant. The truck looks great but I would like to give it sort of a "booster" shot with Jett. Will it seal over a QD like 425? My guess is that if the QD is acrylic/polymer base rather than carnuba it will work - but I'm not sure.
 
So far have not tried using 425 before AJ but I have applied AJ over Quick Wask from JW with no problem.
