Problem: This product is not for use on exterior surfaces. as you learned by the water droplets.
I assume that this is an interior door but none the less, it will be a real pain in the rump removing the water spots.
There are varying views on here and I am of the opinion that wax only belongs on a hard finish, no matter what the manufacturer says.
You now cannot apply a hard finish like urethane or varnish unless this door is completely stripped. So, in the future watch for splashes from soda or beer cans.
