dear jugnu bhai
mother syn is not aio or cleaner wax, aol i.e all in one means ablility of :
1) cleans the surface
2) polish the paint to a high gloss
3) leave behind a layer of protection
best example is megs cleaner wax.
every wax has very minor cleaning agents but not as strong as specialized cleaner waxes as example stated above, its also depend on ur application style i.e u wish to use it for filler or for gloss or for sealent etc.
well its usman bhai's best combination i.e syn over natural, my self and many of others here also following same combination and very satisfied.
mother syn wax or megs nxt dont have such cleaning agents who can eat natural wax layer underneath.
would request usman bhai to further elaborate his expert advice.
