ur car needs good massage with this cleaner wax, use moist foam applicator pad, work on a 1x 1 feet area, good massage with modrate pressure, once u cover whole one pannal, buff out with moist microfiber.
once u done whole car give couple of hours curing time than repeat same procedure, now u have prepared skin to seal it with good wax ( since u have light colour so synthetic wax would be good choice in term of longer protection and good reflections )
the best part of synthetic wax is its dont attract much dust
