cut hole in aluminum siding for bathroom vent fan

My house has aluminum siding. I want to install a bathroom vent fan that vents to the exterior of the house, straight through the wall. Once I cut the hole for the vent, what's the proper way to finish up the hole so the siding remains waterproof?

A ceiling mount that vents out or a thru the wall mount ?

This is the wall mount that I use.
Comes as a complete kit with the outside hood and damper. The hood gets attached and weatherproofed to the siding.

Thanks for the reply! It will be on a wall, an exterior wall. Right above the shower, direct to the outside.

If possible I would pick a spot that is centered on a row of siding... so if you have 7" siding, for example, drill your hole 3 1/2" from the top or bottom edge of a row... so that when you install your vent you can just caulk around it without having to worry about the vent sitting over 2 different pieces of lap siding.

If you have no overhang (wide soffit) you would obviously need to use a vent fan that is louvered, or rain will get driven right into the fan.

Yes.... sidewall venting can be an issue. One good thing about the Panasonic fan is it comes with a downwards pointing vent cap.

How about a siding block?

Just not a great plan.
What's above this area?
Is there a second story, or attic?
