Hey everyone right now i'm gathering supplies as i get ready to get started on my Galactic Marine armor. I plan to use Aqua Resin however i was looking at some pictures and i saw that sometimes after the Aqua-Resin is applied sometimes it doesn't have a smooth finish, i've heard to fix this ppl use bondo but i'd prefer not use Bondo does anyone know what i can do if it is the case that Aqua-Resin doesn't have a smooth finish? And not have to use bondo.
