My personal favorite glaze is Wet Glaze 2.0. It contains no fillers so corrected, polished paint is best. WG 2.0 is a pure gloss enhancer that produces depth, gloss, and dripping wet reflections!
"Wet Glaze 2.0 is made with acrylic polymers that form a very strong bond to the vehicles surface so you are sure it will not wash away like other glazes.
The polymers also allow Wet Glaze 2.0 to do something that you can't even think about doing with other glazes, they allow it to be topped with a wax or sealant without any bonding or application issues!"
Layering...
As stated, you can layer below and/or above your wax or sealant. I've done 2-3 layers directly on the paint then applied my sealant of choice. For that Saturday night out I apply one or two layers on top.
Yes, it has polymers. However, the term 'glaze' gives away that it fills. If a product doesn't fill, it cannot be a glaze. Check the data sheet, wg2.0 has plenty of filling beyond the polymers.
Oh and unless something has changed, the polymers are not acrylic...
