Need advice on my paint

[s2krank]

Hi, this is my first post on the Autogeek forum :o.

I am sure you guys get this all the time but I need advice on what to do about my paint. Admittedly I am a novice and aside from washing techniques i know relativity little about paint correction.

OK so my paint has always been not in the best shape but recently I went away on vacation and came back to my car covered in water spots :eek:
I tried using a vinegar mixture and a water spot removing gel but neither have proved successful, so I am thinking about purchasing a buffer for my car.

Here are some pictures

And here is a picture of the trunk lid. Honestly i dont know whats going on here, I think its oxidation.

anyways any help is appreciated.

sounds like the paint could use a good decontamination and machine polishing. here's some good info to check out. btw, welcome!
