I'm glad you did this. I have a piece of the crappy MDF "CHIP BOARD" that I had Nailed over a hole on the side of my house. It was there for almost a year. 4 seasons of Okie weather. I sealed it only using the formula but did NOT use the follow up coats of full strength poly. That stuff, as most of you know, usually swells up and breaks apart when moisture gets to it. I think you'll be amazed when you see it. Again, thanks for posting the pics, I for one am not at all surprised with your results especially since you have the full strength marine varnish on it.
