Yep kind of,
Grind fill sand.
Depending on scratches you can use west with filler (powder) to make a paste it is much harder then everclear. Use that first the prime.
Use everclear after the clear to spot and touch up.
West = epoxy
everclear = soft bondo/paint
But like I said I’m anal everclear is fine but not as hard.
If you look at the website
http://www.themanshed.net/supercat-20.html on Craig’s Supercat 20 picture 12-06-08-1458 you see fiberglass, primer, west with filler (Tan old tape stripe), and blue (everclear). On 1457 you see the fairing with west/filler.
Oh yeah--make sure you wear at least a white dust mask.
