Mothers California Gold Wax 16oz

My car is dark blue(lapis blue pearl). Parked outdoors 24/7(no garage) and washed at the self service station every 2 or 3 weeks(usually it's just a high pressure rinse, every month I give it the soap brush treatment, I know it's bad but it's my only option) Application and removal was easy. But it did leave an oily sheen on the car, which attracted dirt and pollen really quickly. I did throughly let it haze up and wiped it clean. I tried wiping a section of the "oil" off and it instantly lost its shine compared to the other parts. This is a brand new car so it's not any sort of paint contamination. The finish only lasted about a month and will require a rewax soon. I wanted a wax that would keep the paint looking glossy and protected for atleast 2-3 months. The only possible cause for this short life span would be the sun, but I'll give this wax another try before I move on. *water beading properties only lasted about 1 week I last waxed the car with this stuff on march 18th 2017. The pics are of may 2nd. Just high pressure rinsed the whole car. No waterbeading at all.
