This is an amazing product, it truly does survive the buff. I wanted to test if it really did survive myself. So I threw a couple lines up on my art wall in the back, let it dry. And a day later went to work with sme white house paint. After 1 coat there was an awesome ghost, so I put up 3 more coats and even then you could still see it, albeit barely, but it was still there and one could still see the lines. This stuff is so amazing I immediately ordered another can.
