Depend if is awlgrip urethane topcoat or awlcraft 2000 acrylic
urethane,the last one is harder and you can buff and polish to macht,
if you are going to use some filler to level the scrachts try to use a blue pigment in the filler, i dont know how big are the spots in your hull
, for smalls scrachts a small brush pencil works nice for me , you cant try with PREVAL sprayer with good results to, mask the area surrounding well....
If you dont know the code color of your hull
, try to take a bit from the scrachts and show up in the shop .
