I am currently working on a 1/35 Bronco Humber. Due to the great interior details provided, I wanted to be able to leave a few hatches open, but could not figure out how I was going to airbrush the model without getting some paint inside, and taping looked for be a very daunting job. So I experimented with attaching the hatches that would be left open in place with a small dot of white glue in each corner. We it seemed the experiment proved viable. After painting the hatches just popped of, leaving very small areas to patch by brush. Now to attach the hatches in the open position, and I will have a great view of all the work I did on the interior.
Not sure if anyone else has tried this method, but thought I would share.
