My objection to MDF, and I've worked with plenty of it, is not all about the end result...it is also the deathly process. Masks and dust collection to prevent inhaling of massive amounts of fine powdered glue and sawdust. One of my greatest pleasures is smelling the fresh cut on a pine board...like that fabled madeleine bringing back memories of my youth, takes me back to the first days, the earliest days, maybe 11 years old and building cabinets with my Dad for our home. Compared to my first smell and experience of MDF, installing trim on steel studs in a commercial job and watching every single one of them mushroom out. It required hours of extra sanding, filling and multiple coats of primer to get right. I've hated it ever since. Every time I use it again, I regret it, panels that bow, shelves that sag. Forget about it...I don't have the time.
