The liquid version is not one that I have used, but the paste version was what I used over my Meguiar's Medallion Premium Paint Protection befor I started using Klasse AIO and 4 Star UPP.
The recommended use for both liquid and paste seems to be similar and it's very likely they give the same results.
IMO, the paste version looked very good and If the liquid does as good a job, you will probably like it.
ive used it... good results. second coat is better. give a real good wet look.
id say its one of the top over the counter products. ive used the liquid version by th way. very easy to buff off and beads really well. super slick. all in all it gives a natural wet shine... would probably look awesome on top of a sealant. on top of like a shinet, plasticky, fake sealant.
oh and it lasts pretty good. i beaded good for about a month and half but then i detailed it again....
