When you're shooting automotive paints through a gravity feed full sized gun you'll usually need a fluid tip in the 1.3 to 1.5 range. The smaller guns use a smaller tip to pass lower viscosity paints and also to match the amount of air designed to flow through the gun. It's really an air to fluid ratio thing. You'll be fine using a 1.3 or 1.4 and adjusting the gun to match the size of the area being sprayed. No need for a touchup gun when doing jambs unless the extra mobility is needed.

If you were to use a 1.0 tip in a full sized gun the air will need to be choked down to match the amount of fluid being delivered, if the fluid tip is so small that the design of the gun won't permit an air setting to match then the combination will not work. The orifices drilled into the aircap are designed to work within a certain range of air volume and pressure.
