Here is the cageI did with por 15
before

I did all the steps, and yes it took a long time.
I did not care for it so much on larger flat surfaces. I had a hard time getting it as smooth as I would have liked without spraying. I only used it on large flat areas where it wouldn't be seen or would be covered. It did self level very nicely on the bars. Maybe with some more practice the flat areas would have looked better.
