Sure, step back to 1200 and sample an area first. If you have orange peel that it takes less than a 1000 to get you might have to shoot more clear. If shooting more clear is indeed the case you should be thinking about some gun adjustments or perhaps reducing that clear some so you don't have as much orange peel.
