If someone covers his metal armor with cloth, can the armor be the target of heat metal?
Does the interpretation of the rules that disallows using heat metal to target armor covered by a garment undermine a positive development of the combat?

Heat metal says:
Choose a manufactured metal object, such as a metal weapon or a suit of heavy or medium metal armor, that you can see within range.
If you cannot see the metal object, you cannot cast heat metal on it.
Say you have a player at your table who picks heat metal and is excited to use it. Don't nerf their choice for no reason. What I mean is, if I chose heat metal, and all of a sudden every armor wearing enemy covered all of their metal armor with XXXXL shirts, and then the DM said I couldn't use heat metal on their armor, I would be very upset - it would undermine a positive development of the combat, so to speak.
Now, suppose I was known throughout the land for using heat metal on my enemies to boil them in their boots, it would be interesting and fun to have one encounter, or even one story arc, where the party deals with a group of enemies that has specifically outfitted themselves to counter my heat metal (perhaps by wearing only leather armor). This would be a neat and interesting encounter that forces me to think outside the box. But it would not be fun if it were all the time.
Don't nerf your players' spell choices, unless there is a temporary, narrative driven reason behind it.
The spell states (emphasis mine):
[...] Choose a manufactured metal object, such as a metal weapon or a suit of heavy or medium metal armor, that you can see within range. [...]
Therefore, you must be able to actually see the metal you wish to cast this spell on when you cast the spell; however, the metal does not have to remain in view after the spell has been cast.
