Looking good Paul I hope all goes well with the dvla as I can sense your angst each time you write about it.I wouldn't worry too much about hand painting your creation as if its not to your standard you can flat it or even do areas again, don't forget all cars used to be hand painted and the queens carriages still are.Have a trial with a foam roller but don't buy the cheap ones as the paint dissolves the glue and the foam falls off. Have you looked at
www.coachpainting.info . I was watching a chap foam roller a narrow boat today and the finish he got was superb, although granted that's his job, and don't forget when it all gets on top of you that your build and willingness to try new tasks has inspired me and no doubt countless others to crack on, I for one log on each day just to check if you have posted any progress.
