Pack Color Kit

Used armor matte sealer on a gundam model kit and want to know how to remove it?
I was paint my perfect grade Zaku and bought some Armory Matte Sealer… and decided that i liked the color of the jet pack and just decided to use the matte sealer to give it a nice look unfortunately i sprayed to close by accident and caused some build up whats a good way to remove this or should i jsut sanded it all off
you can try going over it with a fine sandpaper, but its not likely this will be fixed smoothly. I recommend trying to sand it down and if that fails perform a custom mod over the spot in question by adding equipment, battle damage, bits, etc and repaint the entire component.
Also from one gundam fan to another could you please tell me whether you consider the Strike Gundam white or a very light gray?
