So I decided to mod the Mega Magnus to make it look like the mandalorian pistol from starwars the clone wars series.I can't seem to paste a picture so your going to have to look it up. I'm looking to make the sides as flat as possible as the lower side's on the Mega Magnus are quite bumpy and full of ridges. Since sanding it would take of all of the exterior plastic, what ways would you guys recommend to fill the gaps?
