Yay more progress! Ari fixed the cracks for me, he filled them in with this white-ish putty filler thingy. He's too kind.
Tomorrow he said I can coat it with white base paint, although it seemed the one I used before has been used up so I have to use another one that is slightly shiny... and he said I have to sand it after coating. Oh well, after that I will coat it in gold spray paint and then I can focus on finishing the rest of the sword.
It certainly looks better now, hahah.
