Paint shine

So I've had the RDX for just over a year now and I want to know is there a way to get that original shine back?

I feel like the paint looks thinner..I am guessing the clear coat wear off over time?

So Is there something I can do at home?

Is there a way to get factory shine?

I am very careful when washing my car but I still get those swirlys


Also, when we got the RDX, I loved the windshield...I barely had to use my wipers..any water was just move up... like a thick layer of oil on the windshield...what kind of application is it and can I do this at home?

If I want to get the factory shine..is it worth taking it to a professional?
Do they put a clear coat?

I just leased the new infiniti Q50 and got the black color...that black is so much deeper/darker compared to our RDX...
