Hi Tom,
Sorry if I wasn't too clear about the new Acrylic Jett: Trigger and how it fits into our line-up. Let me elaborate!
A brief history of the product may help.
1st Generation. The original Acrylic Jett formula was released as a non-spray, traditionally-applied sealant. It quickly became our most popular product!
2nd Generation (current product). In an effort to make A.Jett even easier to apply, we tweaked the formula to help make it more sprayable (but not so much that fans of the 1st gen would be offended!). We shipped A.Jett with the standard dispensing cap and included a trigger sprayer with every bottle so that people could choose how they wished to apply it.
3rd Generation (upcoming). Even though A.Jett provides outstanding results applied either way, it is still a rather thick formula for spraying. Instead of atomizing properly, it tends to stream/spit out of the sprayer. I wanted to advance the formula to make it even quicker and easier to get that outstanding A.Jett look. In order to achieve this, we needed to reduce the viscosity to get the product to spray better, but it was imperative to maintain the same high concentration of active ingredients. So, the specific blend of ingredients needed to be tweaked to achieve the reduced viscosity. We took this as an opportunity to also explore ways to make the product even wetter and slicker. The result was the Trigger formula.
However, the original, thicker A.Jett formula is such a good product in its own right and has such a loyal following, we didn't want this new version to replace it. So, instead of having one version of A.Jett that tries to please everyone through compromises, we decided the best course of action was to offer 2 versions that compliment each other but can be maximized for their individual roles.
Acrylic Jett ... the original, thicker, non-spray, traditionally-applied sealant that has produced a loyal following of fans Acrylic Jett: Trigger ... the all-out, no-compromises, 3rd generation, fully-sprayable version
Both are independent last-step, purely-protective products which can be used directly over Prime. You do not need both. Either one alone will provide outstanding results. However, A.Jett: Trigger is so easy to use, it makes an excellent product to quickly add a full refresh layer over A.Jett, if desired (sort of like you would use the Sonus Glanz). It is a versatile product.
As always, feel free to ask any further questions.
Happy Detailing!
Jeff
