Can you double up on it if it's not thick enough?

Yes you should be able to with it being sticky it will stick to itself and double the thickness

Does it keep dust out?

i used it on my comp , & i haven't had any problems with dust. just be sure to seal it tight when using it. Darlene.

Could this be used to fill gaps between door sides and frame where bugs are coming in?

I believe so; we used this to fill a gap around our door. The intent was to keep the cold air from coming in during the winter months, but it works to seal the gap, preventing anything from coming in/out (air, bugs, etc.).

is this double stick?

if you mean double sided adhesive, the answer is no
