    Ken, It definatly sounds like a plus for painted projects and stained ones if I plan ahead, sealer and chip protection. I wonder if it would do anything to help MDF? painted not stained of course. Has anyone tried this to harden MDF?

    Mike,
    I have used the hardener on MDF with mixed results; I found that it was necessary to lightly sand it with 220 or 240 grit to scuff the smooth surface. The formaldehyde resins and wax they use to make the Medium Density Fiberboard acts as a light sealer on the surface. They also make a commercial High Density Fiberboard, that is about 3 times the price, and it’s as hard as Phenolic to work with. (The large amounts of dust they both generate is considered a health hazard) It’s a poor photo that I've posted before but this is MDF with hardener being carved.
