New to painting

I just bought a air tank and paint gun and so on and so forth, I am wondering about any advice anyone could give me for a first time paint job, I'm going to be painting a 1990 Buick Century and just need some noob advice. And help will be appreciated.

My suggestion is use the search. I have covered these questions many many times. Also, paint a car for your first time is not a wise idea. Start off on practice panels.

well I have perfected a spray painting technique working with separate fenders and shit like that, I have even primed down an entire caprice classic using grey spray paint primer and it looks just as good as some body shops prep work and they use spray guns, so I figured I'd give it a try!
