Can i apply the original Jeffs werkstatt, "Acrylic Jett " sealant, the same way as the ( Acrylic Jett "Trigger" ) by just adding a sprayer to the bottle ????

I dont think thats going to work. The Jett Trigger formula is designed to spray while the acrylic jett isnt.

What's the difference,..it's liquid enough ?? Mist on ,..spread with foam applicator and buff

The trigger is easier to apply and generally easier to use. But it does seem to be a variant of the jett formula. So i dont think putting jett into a spray bottle is the same as the trigger.
