These people had someone supposedly strip and wax the place before and they said there was no comparison to the job I did compared to the last one. The corners and edges were noticed right away. The shine is something they hadn't seen on the floor ever. I think most people who do vct around here put 2 maybe 3 coats on in the beginning and most if not all never do a complete strip, just scrub recoat and call it a strip job. And I seriously doubt any buffers are used in a scrub job. One guy around here that I know of that does this work, I've never seen have a buffer.
