"Car sales tactics"
I know where you're coming from Jesse.
You refer to perhaps one refinishing. You will need at least 3mm as the wear layer/veneer. What so many people are ignorant of is getting past the bevels or micro bevels during a refinish procedure.
All products are different as you well know. When refinishing any micro beveled floor it has to be taken out, unless you have a perfectly flat subfloor to begin with and a highly skilled pro that can handle the task.
One of my YT videos on the subject. I had fun creating these videos with a spokesperson named "Jigsaw" a brindle boxer.
