Also regarding Waterlox.
I don't think the sealer ( first coat ) or stuff that comes in the square can needs to be shaken. I surmise that shaking it will make it gel sooner too. The finish that comes in the round can needs to be shaken, as the flateners for the satin finish settle rather quickly to the bottom of the can. So if you do not shake a satin finish you will have a glossy finish. Perhaps that is why they put that one in the round cans so it can go in the shaker.
I find the finish ( round cans ) will not gel nearly as easily as the sealer in the square cans.
This could all be written on the cans ... but I can't read text that small anymore.
