I taped and marked this bottle since new.
Lousy pic but you should be able to get the idea.
You can see the first two marks when I used way too much, but since then there is barely room for a mark between uses.
This bottle has been used on a Vette, Maxima, Accord, and two ext cab Silverados.
I always apply indoors, and I apply directly to a dedicated ZCS pad.
This works for me.
