Car/ Body Protection

I dunno where to post this. So, move when appropriate.

My ZHP does not have a luxury of a shade at work. Short of bringing and putting on my car cover...which might grow legs. How long can our cars last under the sun? Putting on wax can only do a partial protection. I'm worried on this since I think my ZHP on her previous life (P.O.s) was always under the sun (evidence of bird droppings). What else can be done to prolong the paint from oxidation or whatever befalls the body?

Good thing I put her in the shade when I get home. Thanks for listening......
