amir bhai i am 101% agree with you, carnuba giving real depth, richness, fullness in col, its giving something wetness and full of live in col, also touch is warm and $exy while synthtic its a new technology, its gives sleekness, give polymer layer on car skin, its atract less dust , gives high shine but without depthness, richness and wet look in col
in simple words you can say carnuba gives warm look and touch and synthtic gives cold dry look and touch
