I take from this that I should go back with more bondo after sanding down the bulk to fill in any areas that are...lacking in bondo.
And yes, I'm a big fan of Lewis and Tolkien. I'm reading LotR for the first time this year on my own and Screwtape for school. Good stuff! Once my Papa finds Mere Christianity (He's got a lot of books so that might take a while, LoL) I'll read that too.
