Yes, i sand blasted then palm sanded the frame (it is steel). Looking back at my calendar, it definately cured for longer than a week before I put it together (more like a month!), with primer, paint, and clear coat.
What wax are you using? Is it more for shine or pro protection? How are you applying it? I ran to lowes and picked up a clear enamal and airbrushed it on with sanding in between and the frame is sitting waiting around.
