Scratch X Q's?????
All of meguiars products have some level of abrasive (you can call and ask them) so layering meguiars products is impossible. Even their waxes cant be truely layered. You might think you are layering them, but you are really just replaceing the previous coat with the current one you are putting on. With that said, when you apply that NXT to the glaze, the NXT is removing the oils from the glaze and then bonding to the polished paint surface.
In Meguiar's line, we offer two types of polishes, cleaner/polishes, which contain a diminishing abrasive, and pure polishes, which are completely non-abrasive and are used solely for the purpose of creating brilliant gloss. Deep Crystal Polish is a pure polish.
Oh ya and everything is a little abrassive because you have to apply it somehow and the applicator itself is going to be a little abrassive, this is why you use microfiber.
