I insert the tip of the Tamiya chrome silver paint marker in the holes and let some of the ink flow then i uce a paint brush the fits in the holes and brush the ink away from the holes(in this case towards the north-eastern part of the plane).
After the silver paint dries i then insert the tip of the weathering gundam marker (GM29) into the holes just like what i did previously then i brush it in the same direction as the first.This gives you a realistic impression of bullet holes...i think
Because the hole was on the engine, the oils from the engine escapes thats why i apply a lot of the marker paint
Some oil splatter on the wings and burned bullet holes
This was a mistake ,i nearly drilled my finger because of this.Just imagine that someone is shootin from our point of view and hit his tail fin and into the planes body
