New MDF for stands

[Majestic_Aquariums]

There is as well a product called Medex. This stuff is an exterior grade, but is expensive-about $60.00/sheet for 3/4" You still have to seal all cut edges, but I have used this product extensively on exterior work in the past with no problems. Can buy it through Winsor Plywood

To look at it, you could almost swear it is MDF, but it cuts harder, and has a better treated surface, and is formed using more hardened resins. As with MDF though, I use a good dust mask when cutting, as I don't think any of it is good for you to breathe.
