there is difference bt wax and polish. polish will remove light clear coat and are abrasive. if you want to use polish use klasse AIN which is non abrasive. polish gives wet look and depth
you dont need to polish frequently bro. give some time to cure new paint at-least month. there is ambiguity regarding to curing time of new car paint. keeping in safe side atleast two week must be given before any paint correction or waxing. use body safe detailer like meguiars mirror 34 during that period. after 2 to 3 weeks polish or use cleaner wax than followed by sealant 2 coats with curing time to be keep in mind followed by wax
you need sealant twice in year same with polish. but wax regularly twice in month.
i can suggest sealant. mirror glaze 21, CG jet seal or klasse, any one. and collinite hybrid wax. collinte is not available, so you can use ultimate paste good for light colors. organic waxes are used for depth in colour, have more shine but they turn light color to pale. moreover organic waxes in term of durability are not preferable as compared to synthetic one
