Orange peel
Getting close to painting my k20. I've read a lot about how to avoid orange peel, but no real fixes or what exactly causes it. I've heard gun settings, travel speed, and temperature are all causes. My question is, if you get orange peel what do you change? Is it too high pressure, too much volume, too low pressure, travel speed too slow or fast. I've sprayed some single stage paints before with little problems. I've never done BC/CC. Just trying to avoid alot of cutting and buffing. Any tips from the pros would be appreciated.

Re: Orange peel
There is 19 different reasons for having orange peel . when you look at a chart it says the pressure is too high, the pressure is too low or too close with the gun . I would suggest painting the backside of a fender or a scrap piece and make your adjustments When you get good flow out THEN PAINT the panels. Sometimes a little extra reducer does the trick
Therefore reducing the amount of cutting and buffing.

Re: Orange peel
The most common causes of "orange peel " in modern CC's ( given the gun is set up correctly ) is going to be moving too fast or the gun too far from the surface. If your moving too fast, the clear will go on too thin and dry, and wont flow out. If your too far away, kinda the same thing. Your just billowing clear over the panel and it goes on dry, unless you really slow down. You need to apply the clear to the panel.

If your in a booth with good lighting. You want to look right at where the clear is hitting the panel or slightly behind, and pay attention to what the clear is actually doing. Whether its flowing out, dry, or too thick, rippling behind the gun. You'll also pick up your cap to surface and overlap reference here. Where you are on the panel, what your hoses are doing, how much clear is still in the cup, ect you pick up in peripherals.

Using too fast of a hardener or reducer for shop conditions. Will also not allow the clear to flow out properly.
