Whilst it would indeed seem that upon getting wet, the water simply runs off the leather, if left in damp humid conditions the leather will go mouldy. It is not advisible to leave leather around too much water, just in case, so whilst the way it is treated means it doesn't absorb water easily, its better to be safe than sorry.
Leather will turn back to normal once it dries. Be careful not to scuff it while it's wet as the scuff will ruin it. Wet leather is not ruined leather.
Yes it does! DO NOT spill water on anything leather because it will rot
Unless treated with something to waterproof it then yes leather will absorb water.

Use a leather cream/cleaner on it. Wetting the leather may make it shrink and ruin it.
You should use a suede cleaning tool and suede or leather cleaning solutions. Do not use water in any form, as this will ruin the leather.
Go buy the leather cleaning products. Otherwise you will ruin your leather.

Leather does not get ruined very easily. it is easy to clean so the mount should not effect the quality of your dashboard. take it to a special place and get it mounted correctly so it wont ruin the leather.
yes it will your leather will begin to fade trust me i got one of my gloves wet before i was so mad

Depends on if the leather is finished, but yes. It'll either literally dissolve and remove the finish on the leather or dry it out badly (best case).
It is TOTALLY worth it. It looks nice and lasts long.But, if it gets wet it will ruin the leather if its not waterproof.
Yes, Leather is made from an animal hide that has pores. It is capable of absorbing water which can lead to dryness and cracking. Although, waterproofing sprays can make your jacket waterproof to some extent that doesn't;t mean you should wear it in the pouring rain. Real leather is expensive so make a full effort to avoid any damage.
You can do it with a torch but great care must be taken, knowing when to stop is the key, you can ruin the leather very easy this way. Good-Luck
Because if they wear leather it might ruin to easly because they are running andleather wioll stink more.
