Yeah, I think ZFX makes a difference, but, only after multiple coats are applied. After the third coat the finish really seems to come alive and "PoP" more than it would with 1 coat of regular polish or ZFX polish. After 3 coats recently on my new G, it really left a heck of a gloss. Also, it really helps speed things up, unrelated to gloss I guess but... Actually, it speeds things up so you can get more gloss....there we go!
