Door panel straihtness

I'm working on my gt4 doors trying to get the skins nice and straight. Looks like this is essentially impossible without lots of bondo which I won't do.the upper skin is fairly straight across but the lower half has lots of variation,up to a quarter inch in places. I think the reason for this variation is the factory door reinforcing bar for the US. Question is is they pretty much normal,I laid a 4 foot steel rule across the skin to determine the variation. What have the rest of you experiences and to what extent of variation you deem acceptable without turning into a body queen. My doors are not damaged and are presently stripped to bare with a coating of primer thanks. Will I find this on the rest of the body?

 

I see I missed spelled straight in the title,due to smart phone inexperience,give me a key board

 

There is this hump in the middle of the door right above the door safety reinforcement and drops down to each edge.above crease line its fine ,lower door panel above panel edge its fine. Its just where the reinforcement is. Will state other door not as bad. Luigi on one side, Marco the other door. Joys of hand made "craftsmanship ship". I'm just trying to make things better and wondering if other s encountered such.

 

This primarily occurs a few inches below the crease line. There is a high spot in the middle due to the door reinforcement. Which then trails downward to the edges appx 1/8 inch on each side. Door has no damage!!! Heat would really screw it up. I did notice many layers of factory primer when stripping it. Sorry can't do pics on this. I know there doors have a bow to it but I'm talking about horizontal straightness across the door. I'll get it as reasonable as possible with high build primers and lots of sanding. Perfection can't be achieved as it is hand built. Saw a 250gto under restoration at Paul Russell's years ago and the restorer told me to look down each side and I'd see they weren't the same!!! Told me he could make them the same but they weren't that way when built. Said that was the hardest part for him not fixing the original faults.
