Just because something sprays 'orange peely' don't...

....go looking for what the product you are spraying 'reduces' or 'thins' with.

I see and hear this everyday but almost everytime it can be corrected with a simple fluid adjustment via the paint gun. Simply turn in clockwise the fluid adjustment knob just above your hand 1/2 turn to start with.

Make another pass either on some masking paper or the vehicle to see how much it helped. If it's still a bit peely make another 1/4 clockwise turn and check again. Repeat if needed.

Whether it's DIY'ers or $100K per year painters I see this mistake everyday and its an easy one to correct. With a simple adjustment you get a nicer job without adding a $40/gallon solvent that you hope is the right temperature/speed for what you are painting.

just to add to what andy said

a painter that is not used to using a HVLP gun (RP users) can have a rought time with orange peal also

a HVLP gun must be held way closer to the car while painting (6" give or take a bit)... too far away and it will orange peal like a mother

Andy also, instead of leaning out your gun by cutting back the paint you can increase the air pressure a bit to increase atomization of the paint.. although be carefull doing that with metalics and pearls they will do some nasty stuff if the air pressure isn't right, and air pressure of the gun (even as little as 5psi) will change the color of the paint, that can be good or bad depending on if your doing a all over or blending a panel
