Not quite sure what you're describing here, but most problems with spraying are usually caused by too much or too little air. If the paint is going on too thick and wet, turn up the pressure. If it's not quite sticking and getting powdery on the edges, turn the pressure down. Also read the labels on your materials and make sure you're mixing in the right proportions.

Make sure there isnt any silicone products in the garage your spraying in. That can cause weird issues with any paint. Let the base coat dry and clean it with acrilye clean or a cleaner made to remove wax and grease from your paint supplier. Then make sure its warm enough in the garage and try again. Oh and when you wipe the car with cleaner wipe the cleaner on with one lint free towel and off with another,dont be cheap use several towels. More info would be helpful..what type of paint PPG,R&M,dupont..HOK?

Can you physically feel the streaks once it dries, or is it level just without pigment in the streaks?
It sounds to me like you have an incompatible primer, or you mixed your color coat to hot, and the solvent is attacking the primer. I had this happen in a few spots when we resprayed my car. Only solution is to let it set up, then wetsand it off. I was able to wetsand mine without burning through the primer (this is why you shoot 6-7 coats of thick primer) and then just respray over it again.
If you are able to just sand and respray, make sure you go VERY LIGHT COATS over those spots for the first 3-4 coats, then go on a little thicker. This will help minimize any solvent incompatiblities.
You didn't use rattle can primer did you?

very true however silicone products cause what is known as "fisheyes". They are small circular indenations which are caused by a pintip sized piece of oil (or silicone) being on the surface when you paint, given the nature of oil and silicone -the paint doesn't stick and it simply flows around the contamination.
Not the problem here.
by the sounds of this problem I would say - without seeing picutres (which would COMPLETELY clarify this problem - wink wink) that your primer has softened, or reflowed if you will, up into the solvent rich base when it was applied
Thats why spray balm primer is ****........assuming thats what you used, if not then please tell me what it was and post some pics

I'm not referring to the TEMPERATURE of the color coat; I'm meaning that he didn't properly measure the ratios and went too heavy on the activator or thinner, causing the solvents to attack the primer. That or the primer hadn't properly set when he shot it.
