dear usman bhai sooo happy to see you after sooo many days without u udasyian he udasyian hain on this thread.
i work in leather tannery and in finishing dept we also use lot of oils, waxs, sealents, even carnuba waxs on leathers, we also play with all waxs, oils, sealeants , glazers and polishers to achive desired touch and optic, some time we do waxs on top and some time where we wish to protect the waxy feel/touch for longer time and to improve colour rub fastness properties we apply sealents on top etc so as per usman bhai and aamir bhai its all depend upon what desired requirements we have in our mind.
as like some people apply carnuba wax on top after synth so synth can also apply on top of carnuba to protect carnuba wax depth for longer time, i personaly tested this theory on my car as like i applied turtle glaze which is quite oily and wet but i top up with turtle synthetic wax on it and i surprise to see the strong binders in it which binds stongly even on oily wet surface on car, in leather we have experince carnuba waxed surface attract dirt and become dirty easily where as if top up synth than surface become too smooth and silky and for dirt particulers its hard to stay on car paint work.
its true synth after carnuba reduces wet look but here we have more pollution / dirt compare to europe and usa so this theory works here great to keep car dirt frree atleast for a week.
