Here is the start of my Rattle Can ESB Wasted Fett Fugly paint up using Rafal Fetts stencils and Superjedis tracing method. I traced the first layer and eyeballed the rest based on the scale of the first layer. It was suggested to me to give it an acetone bath and a bubble bath. This is valuable info as the paint may not adhere if not prepped properly. Trimming was done carefully with a Dremel as suggested by the legend BudaFett.
All imperfections in the cast were filled with spot putty from an auto parts store. It comes in a tube, not the big can like you would use for bigger sections on 3D armor. I left the bridge between the visor as it was also suggested to keep the shape and to avoid warping of any kind in the visor area. I just wanted to provide this info because this is my first cast helmet paint job and I didn't know any of this before starting.
