Didn't take long for the holes to fill with oil again.

The rest of it has to be frequently cleaned of oil to get it to assemble.  Alcohol dissolves the sharpie ink.  With the oily buildup, the black paint doesn't do it for lions.  Maybe it would if real used starships were a common sight. 

The oil eventually makes the unpainted side as dark as the painted side. The heat eventually delaminates the layers & they break off.  They can be glued back together.  Looks like either the diameter needs to go back up or it needs the stringers.
