I'm starting my first ever armor build with a Shoretrooper helmet from Imperial Surplus, but I'm a little unsure where to start. I've found a lot of paint tutorials, but the Imperial Surplus helmet has some extra plastic bits around the inside bottom of the helmet and where the see through visor is supposed to go. Is there a recommended way to cut out the excess plastic and install the see-through plastic, or any helpful tools I should consider getting? If there's already a guide for this, a point in that direction would be great.
Thanks in advance for any and all advice!
