Painting cab in stages

[WB72]

I am going to be priming then painting my cab inside and out. I don’t have the ability to do it all at once, so I will need to do it in stages.

I have a cradle that my cab sits on and I have an overhead crane that I can hang it from temporarily.

I was thinking that I should do it in this order:
Hang the cab, spray the bottom outside and firewall.
Set it back on the cradle.
Spray the inside, then the door jams and window openings.
Mask the inside and firewall.
Spray the exterior. (paint will be sprayed at the same time as the rest of he body panels but I want the primer and interior done prior to aligning panels and painting)

For those with experience with this, is this a smart way of doing this. I am estemating this will take 3 days for me to do simply because I need to work on it during spare time only and I have to allow time to dry prior to the next area of spray.

I will be working with epoxy primer and then single stage paint for the colour.
