OK, there's more to spraying than I can type here. But confidence is easy to take care of.

Get some cheap paint and whatever you need to thin it with. Get something non porous and start spraying.

Here's the basics of what you need to know:

1) It doesn't matter what PSI your compressor is at. What matters is that YOU like how the gun is spraying. I've sprayed from 15 to 60 PSI depending on what I was doing and how the paint was going on. There are no rules here.

2) Thin the paint so that YOU like how it sprays. I've used up to 75% thinner. Normally I use 30 - 50% but just try the paint on something and adjust it until you like how it sprays. In other words, after you have mixed your paint do not thin all of it because you might want to add some in to thicken it if you think you've thinned it too much. Hope that makes sense.

3) Use a real degreaser before you paint. Don't use dishwashing soap. It contains chemicals that may cause fisheyes in your paint.

4) Practice, practice, practice.

Don't let all that PSI/thinner ratio stuff scare you. It's all what you like and NEVER EVER start painting your model until you like how the gun is spraying.

PS. I've used Perfect paints. They peeled off the primer. Hours and hours of wet sanding and polishing down the tubes.
