Skinny,
Might be too late in your though process but I can highly recommend Steel It to paint the chassis with. Looks good, goes on well - seems fairly durable going by my ham fisted attempts at fitting components, and best of all you can weld through it if you do happen to forget to weld the captive nuts on for the fuel tank...
You are definitely a dab hand at this blasting lark. Looking forward to the next update.
P.
