In one of the pics above you can see the stock top and rear
covers, too high and full of holes... After sanding my MDF mold
I primered it and gave it a quick layer of paint to help find
any imperfections. The left side looked okay but the right side
looked a bit wavy. After holding a ruler against crankcases
and MDF mold, I found that the "wavyness" started
in the right side of the crankcase itself.
