They are super fine cracks in the existing paint, like maybe the thickness of a sheet of paper or less. Maybe some 1k spot putty and then more epoxy? I tried to sand them out, but I didnt get down that deep. When I sprayed my epoxy on, I noticed immediately that it didnt want to fill them for some reason, like it drew away from them.
For that reason, I really only have like 1 coat of epoxy on the nose, I didnt want to keep piling it on and then have to sand it all back off, because I wasnt sure what the fix would be.
