Don't worry guys, I'm not really going to scrap it, I have too many hours in it to do that. Having said that, when I was about 1/3rd the way through and the top ply began coming off, I came close to chucking it in the bin. If you click the photo to enlarge it, you can see the damage at the top of the cab directly above the front left wheel. I was originally going to give it to the owner of the bus, (assuming he would accept it), but I'm not happy enough with it to give it away so I'll keep it for myself.
Thanks for all the comments.
Martin.
