This
set, for the HK Models 1/48 B-25J Mitchell is quite comprehensive. It
includes both inner and outer masks for all the clear pieces as well as
masks for the wheels. As such it comes on three different sheets of kabuki
tape masks. As normal with their sets, it comes with a full set of placement
instructions as you can see by the included image. I have often wondered if
one could use the inner masks on the outside as well. If any of you have
done this with success let me know. I rarely mask the inside, finding it
easier to paint the interior color on the outside before applying the
exterior camouflage.
