Reading the discussion on filling the edges of MDF started me thinking about using that same material for a knock-down bookcase for my granddaughter bedroom. I have tried to steer my kids away for the dark brown finishes that a popular now days to no avail. Since I think it might have a limited life I thought the use of a less expensive material might be just the ticket. IKEA sells tons of the stuff. I don't have a source for a grain pattern MDF so I thought if I primed the MDF with a oil based primer then use a graining tool on either a gel stain or glazing to create the illusion of wood before sealing it with a top coat might work? I was going to try it but thought I ask just in case I've spent to much time alone in my basement shop. Thanks.
