In that case, diluted spray sealants like GTechniq C2v3, Gyeon Cure, CarPro Reload or even the sealant marketed ad a detailer in Sonax BSD will all be infinitely better than Project 32. GTechniq now even sell C2v3 pre-diluted as a QD (in case you like paying for water...).
That said, personally I find it hard to look past Gyeon Wetcoat or CarPro HydrO2 for touchless top ups - why spend the time and effort applying then buffing a product when you can literally spray on, rinse off and go?! Or better still Gyeon Bathe+, which adds protection whilst you're washing. These both have the advantage that they're not fussy about what they bond too (unlike the aforementioned spray sealants), they'll last a damn sight longer than a QD and they both add noticeable gloss with absolute minimal effort and risk of marring.
