that vent did come out nice. if it was me i wouldn't be too concerned about some scratches and pitting etc, after all the case has been attacked by zombies... and we all know that zombies scratch and tear when they try and grab hold of something. i would just chalk some imperfections as adding to the look as it were. plus i'm lazy about those sorts of things. also i was at hobby lobby the other day and they had some cemetary scenrery for whatever scale lionel trains were that looked half decent. if you have those stores where you live you might take a look and see if they have any. i believe they were like $1.99 for like 10 or so. it would save alot of time making them all.
