Gapping Doors

[Scubachef]

I have a question about setting gaps and placement on the doors for my 69 camaro. I’ve removed the doors and hinges. Hinges got blasted, rebuilt and sprayed with epoxy sealer. The door jamb has been stripped and sealed. I’m getting ready to get all the gaps and placement as perfect as I can and I’ve got a plan that has one hole I can’t figure out. When I take this all apart to paint the door jamb and hinges won’t the thickness of the paint on both change how everything fits or is this not going to be a noticeable issue? If it will change everything what are some tricks to accounting for the extra thickness. I thought of putting layers of masking tape between the pieces to simulate the thickness of the paint but I’m guessing on mil thickness? Is this a dumb idea, a good one, or is this not anything I actually have to consider? Thanks.
