Yes you can base over your repaired area then clear the whole panel ,just make sure you leave enough room to blend out your color.You need a min. of 18 inches is recomended but depending on the color the area,body lines etc. you can bend the rules a little.As far as making the undamaged panel look fresh 500 grit is a little coarse in my opinion we use a min of 800.The only thing I don't like about this method is that it takes the factory orange peel away and the new coat of clear goes on much smoother than the rest of the car making it look repared.Try some stuff called blend prep it is fast and does not cut too deep.If you just want to freshin it up try polishing it good luck and I hope this helps
