ASSEMBLY ORDER QUESTION

It's much easier to put the bolt on panels back on & align all the gaps before the final paint is on the car, but yes, I would blow in all the jambs & hidden spots first while it's apart, but that's just me. Some paint the fenders, doors, trunk, hood etc. off the car, but if that's done, be sure the panels are painted in the same way/direction as when the are attached to the car with metallic paint, so the paint lay's out like it would when it's bolted on, otherwise the shade of paint could be off & not match with the body of the car. Metallic paint is kinda' tricky unless your pretty good at it.
