Freds 73 Scamp restore on a budget

Yea I would guess with the suit and fresh air that would make a big difference but as you well know we on a budget do what we can.
I'm Gonna be painting my sons plane here soon I think any suggestions on paint to use.
Every plane part we build is painted with DEFT brand paint, it is a mil spec paint, if I remember tomorrow I can get the mil spec numbers.
It is pretty much industry standard, lightweight paint, that holds up to elements and corrosion.
