Liquid vinyl coating

Anyone had any experience with type of coating

I sat thru a sales pitch and researched it 10 years ago or so when I was running paint crews as well as washing. We passed on it. If the prep is not perfect it won’t adhere, plus, if you trap any moisture behind it it will not the interior. Never washed any or even been called to was one. Something I’d walk away from probably

I washed it yesterday with no problems. Customer wants her deck redone it needs to be stripped before it can be repainted. They stained it and then years later painted it so it peeling no big deal we do deck restoration all the time. I’m just going to cover the whole side of the house with plastic. Just curious if anyone has run into this stuff
I called company that did the application and they had no information for me.
