Oh my gosh. I stopped using Tamiya clears because I felt like I was using less than 1/3 of the can and inhaling/wasting the rest in an attempt to not over saturate. Modgepodge acrylic spray might be worth a try. I used it to seal some plaster recently on a build recently...and then used it to seal the whole damn thing when it was done because it was so easy to use.
