So I started unpainting some wings that I picked up. At first look it seemed things were going well. However now I am seeing some parts that look a darker gray. There must be some paint that I havent removed yet cause it cant be that parts are black and others are gray. Also, has anyone buffed the wings after, cause it seems that there may be some scratches on them that wasnt visible with the paint on.

Does anyone have any solutions/suggestion for this?
