You can scuff it with gray scotch bright pad or 600 - 800 grit sand paper. I would block sand it unless you have a DA sander with a soft pad. You can break through the clear a lot easer with a DA. So if your not use to using one I would block sand it. From what I can see from the pictures you have some orange peel, so I would block sand it to get as much as the orange peel out. The smoother you can get it the better the next coat of clear will flow out for ya. I would recommend 2 more coats of clear. If you do 2 more you will be happier with the outcome. What air pressure is at your gun when you spray ?
