mere peyare bhai u are also right, differnt ways of application leaves differnt optic and effect.
as per words of v1
if u need beauty than first synthtic and later carnuba but if u prefer for protection than 1st carnuba and than synthtic
about synthtic i tell u it having great sticking properties, first time i applied ample qty of glaze and failed to properly message and penitrate into car skin , glaze having differnt oils and i applied synthtic on that oily / wet surface of car and wonder still it caught the surface, just try it and see the wonders
if u need beauty with protection also than go for this combination..
carnuba -- synthtic-- carnuba detailer spray
