first thing is to make sure your gun is spraying right. You want a nice even pattern. Dont back the fluid out to far. My guns are set up so that the fluid is set in pretty far. To much fluid and it will have more orange peel. You want less fluid so the gun can atomize the paint to make to orange peel smaller. Hold your gun about six to eight inches from the panel and overlap about 50 to 75 percent. You also want to make sure that everything that you apply goes on as smooth as possible also. If your sealer and base go on dry and orange peelly, then your clear will also. Dont put you base on to wet , you want a 75 percent wet to dry look. use the proper reducers also. Too fast a reducer and it wont have time to lay down. Even though you want a somewhat wet look for your base and sealer, apply it in as thin of coats as you can. To heavy of coats and ith will just build up to thick. More thin coats are better then less thicker coats. Give everything the proper flash times also. Cutting flash times can make paint not adhere as well. It will also cause the clear to shrink and cause it to look like orange peel. A lot of how your clear looks depends on how you apply everything else. Hope I didn't confuse you. good luck.
