68 barracuda 383s "Driver Paint Resto"

Seeing that I am limited to time to spend on the car I was thinking if I start stripping 1 panel at a time. So say if I get a fender and door stripped in one night, how long can I let it sit before I get a coat of epoxy on the bare metal ? I should add that I will be doing all the work in my garage in Ontario Canada in summer like temperatures.. thanks
