No matter what type of paint you may be spraying, it's a smart thing to wear a good respirator. NOT one of those cheezy cheap-o semi-dust filters you might see folks wearing while mowing the grass or strolling the streets of Bejing. Eye protection is also wise.
The pilot light in a gas water heater installed in or near a garage paint booth has brought to grief several solvent-based paint spray folks. Don't be that guy.
I've 'shot' a couple of aircraft, a few cars and motorcycles using a variety of paint chemistry. Best advice I can give to anyone is this: Spraying color is the easy part. Any sags, runs, orange peel or stray gnats can be wet sanded away after the color has cured and prior to any clear coats.
Sand, sand and sand the old paint, Fill any deep scratches on small dings. Prime and dry sand 2-3 coats. Shoot a coat of sealer and you should not see any flaws. Then, it's color time! Solid prep work results in a quality paint job you'll be proud to say, "I did it."
BTW, it ain't brain surgery. Just take your time.
