I recently painted my car. Base coat went on nicely, until I applied the clear. Unfortunately there is orange peel on the one side, and on the hood. I am fairly new to painting cars but this is not the first car I have painted. What is the best way to resolve this issue? Do I need to re-sand and start from the top, or can I wet sand the clear and then respray the clear? As I say I am fairly new to the trade. I am using a siphon fed gun, should I be using a gravity fed gun? Any information would be greatly appreciated.
