You mention covering foam. Is that to imply the final will be electric? If so, what covering are you using? I found Monokote is strong, but can be harder to work with, particularly around compound curves. Sig makes a product - Aerocoat- that is lighter than Monokote (not as strong), but is designed for lower temperature applications (like foam). It stretches easier around curves with lower heat. The adhesive is also not as strong as Monokote, but its designed for lightweight electrics and foam, so you might find it easier to work with on your next project (there's always a next project).

Looking good.
