Not sure what I am doing wrong, Please help.

I am attempting to paint half my car due to clear coat peeling and was told to first try using a preval sprayer with car paint, sanded, painted, cleared and it looked pretty bad. So bought more paint, clear coat with hardener, Devilbiss flg4 gun, sanded all the paint I just put on with the preval off and had to spot primer a few places due to went through to mental. Painted the car with the spray gun and it looks worse, I am not sure if it is how I am using the gun or my prep work on the car. The paint now looks very blotchy and as if I did not even paint some spots but I am certain I sprayed it a few times and by spots I mean large areas. I had only a few runs but not too many. The paint looks very good in some spots but awful in others. What could I be doing wrong and how could I improve it? Is it me and the gun or bad prep? I just want to get it wright.
Thank You,
Derek

First off, anyone that tells you that you "should paint a car" with a spray can sprayer should be shot! Obviously they've never sprayed a car before.
As far as what you are doing wrong, there are many things that could have gone wrong. My first idea was that the old paint started wrinkling on you to make it appear blotchy, but that can't be the case because you stripped it off. Sounds like you are trying to do this job cheap, so possibly you used cheap primer. Did the primer have a catalyst, or was this spray can primer?

Or, the blotches could be just the way you sprayed it. Possibly you thought that the spray gun should spray like a Preval sprayer.
Is this a metallic or solid color? What paint did you use?

Anyway you can take pics and post them? This would help. Maybe this will give us a better idea?

Thank you for your help I really appreciate it, for the primer I used a spray can primer that I got from the place I got the paint from. The paint is limco paint and is a silver metallic and i got axis clearcoat that I did not put on yet since the paint looked so bad. I will post some pictures up today. I am trying to do this cheaper but want to do it correctly. Thanks again

Spraying Limco over spray can primer shouldn't be a problem or unless you put the primer on very dry or something like that.
Probable cause is spray technique, but once you post the pics, that will help.
