Thanks for the tips - While they are usefrul and I'll retain them for future use, what I had intended to ask about was either preventing dust from collecting on a finished model once it is on the display shelf - or if it does get dust on it on the shelf, what is the safest way to remove said dust.
I used to build 1/700 ships, and what detail the kits did provide was quite fragile. My cruiser Takao, with its pagoda superstructure, now looks like a dinghy with no superstructure at all - cranes and floatplanes were the first to go when my wife dusted, then turrets, and then the entire superstructure mysteriously moved itself to the shelf below. So I'd love to find a way to keep this from happening and also to just keep the dust from obscuring all the fine details on my ships - or aircraft.
